feat(tests): Implement comprehensive testing framework for telemetry system

Implement a privacy-first, provider-agnostic telemetry system to help improve Crawl4AI stability
through anonymous crash reporting. The system is designed with user privacy as the top priority,
collecting only exception information without any PII, URLs, or crawled content.

Architecture & Design:
- Provider-agnostic architecture with base TelemetryProvider interface
- Sentry as the initial provider implementation with easy extensibility
- Separate handling for sync and async code paths
- Environment-aware behavior (CLI, Docker, Jupyter/Colab)

Key Features:
- Opt-in by default for CLI/library usage with interactive consent prompt
- Opt-out by default for Docker/API server (enabled unless CRAWL4AI_TELEMETRY=0)
- Jupyter/Colab support with widget-based consent (fallback to code snippets)
- Persistent consent storage in ~/.crawl4ai/config.json
- Optional email collection for critical issue follow-up

CLI Integration:
- `crwl telemetry enable [--email <email>] [--once]` - Enable telemetry
- `crwl telemetry disable` - Disable telemetry
- `crwl telemetry status` - Check current status

Python API:
- Decorators: @telemetry_decorator, @async_telemetry_decorator
- Context managers: telemetry_context(), async_telemetry_context()
- Manual capture: capture_exception(exc, context)
- Control: telemetry.enable(), telemetry.disable(), telemetry.status()

Privacy Safeguards:
- No URL collection
- No request/response data
- No authentication tokens or cookies
- No crawled content
- Automatic sanitization of sensitive fields
- Local consent storage only

Testing:
- Comprehensive test suite with 15 test cases
- Coverage for all environments and consent flows
- Mock providers for testing without external dependencies

Documentation:
- Detailed documentation in docs/md_v2/core/telemetry.md
- Added to mkdocs navigation under Core section
- Privacy commitment and FAQ included
- Examples for all usage patterns

Installation:
- Optional dependency: pip install crawl4ai[telemetry]
- Graceful degradation if sentry-sdk not installed
- Added to pyproject.toml optional dependencies
- Docker requirements updated

Integration Points:
- AsyncWebCrawler: Automatic exception capture in arun() and aprocess_html()
- Docker server: Automatic initialization with environment control
- Global exception handler for uncaught exceptions (CLI only)

This implementation provides valuable error insights to improve Crawl4AI while maintaining
complete transparency and user control over data collection.

+## 🕵️ Undetected Browser Support: Stealth Mode Activated
+
+**The Problem:** Modern websites employ sophisticated bot detection systems. Cloudflare, Akamai, and custom solutions block automated crawlers, limiting access to valuable content.
+
+**My Solution:** I implemented undetected browser support with a flexible adapter pattern. Now Crawl4AI can bypass most bot detection systems using stealth techniques.
+
+### Technical Implementation
+
+```python
+from crawl4ai import AsyncWebCrawler, BrowserConfig
+
+# Enable undetected mode for stealth crawling
+browser_config = BrowserConfig(
+    browser_type="undetected",  # Use undetected Chrome
+    headless=True,              # Can run headless with stealth
+    extra_args=[
+        "--disable-blink-features=AutomationControlled",
+        "--disable-web-security",
+        "--disable-features=VizDisplayCompositor"
+    ]
+)
+
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    # This will bypass most bot detection systems
+    result = await crawler.arun("https://protected-site.com")
+    
+    if result.success:
+        print("✅ Successfully bypassed bot detection!")
+        print(f"Content length: {len(result.markdown)}")
+```

+```python
+# Combine multiple stealth techniques
+from crawl4ai import CrawlerRunConfig

+- **Content Aggregation**: Collect news and social media despite anti-bot measures
+- **Compliance Testing**: Verify your own site's bot protection effectiveness
+
+## 🧠 Memory Monitoring & Optimization
+
+**The Problem:** Long-running crawl sessions consuming excessive memory, especially when processing large batches or heavy JavaScript sites.
+
+**My Solution:** Built comprehensive memory monitoring and optimization utilities that track usage patterns and provide actionable insights.
+
+### Memory Tracking Implementation
+
+```python
+from crawl4ai.memory_utils import MemoryMonitor, get_memory_info
+
+# Monitor memory during crawling
+monitor = MemoryMonitor()
+
+async with AsyncWebCrawler() as crawler:
+    # Start monitoring
+    monitor.start_monitoring()
+    
+    # Perform memory-intensive operations
+    results = await crawler.arun_many([
+        "https://heavy-js-site.com",
+        "https://large-images-site.com", 
+        "https://dynamic-content-site.com"
+    ])
+    
+    # Get detailed memory report
+    memory_report = monitor.get_report()
+    print(f"Peak memory usage: {memory_report['peak_mb']:.1f} MB")
+    print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
+    
+    # Automatic cleanup suggestions
+    if memory_report['peak_mb'] > 1000:  # > 1GB
+        print("💡 Consider batch size optimization")
+        print("💡 Enable aggressive garbage collection")
+```
+
+**Expected Real-World Impact:**
+- **Production Stability**: Prevent memory-related crashes in long-running services
+- **Cost Optimization**: Right-size server resources based on actual usage
+- **Performance Tuning**: Identify memory bottlenecks and optimization opportunities
+- **Scalability Planning**: Understand memory patterns for horizontal scaling
+
+## 📊 Enhanced Table Extraction
+
+**The Problem:** Table data was accessed through the generic `result.media` interface, making DataFrame conversion cumbersome and unclear.
+
+**My Solution:** Dedicated `result.tables` interface with direct DataFrame conversion and improved detection algorithms.
+
+### New Table Access Pattern
+
+```python
+# Old way (deprecated)
+# tables_data = result.media.get('tables', [])
+
+# New way (v0.7.3+)
+result = await crawler.arun("https://site-with-tables.com")
+
+# Direct table access
+if result.tables:
+    print(f"Found {len(result.tables)} tables")
+    
+    # Convert to pandas DataFrame instantly
+    import pandas as pd
+    
+    for i, table in enumerate(result.tables):
+        df = pd.DataFrame(table['data'])
+        print(f"Table {i}: {df.shape[0]} rows × {df.shape[1]} columns")
+        print(df.head())
+        
+        # Table metadata
+        print(f"Source: {table.get('source_xpath', 'Unknown')}")
+        print(f"Headers: {table.get('headers', [])}")
+```
+
+**Expected Real-World Impact:**
+- **Data Analysis**: Faster transition from web data to analysis-ready DataFrames
+- **ETL Pipelines**: Cleaner integration with data processing workflows
+- **Reporting**: Simplified table extraction for automated reporting systems

+
+## 🚀 LLMTableExtraction: Revolutionary Table Processing
+
+**The Problem:** Complex tables with rowspan, colspan, nested structures, or massive datasets that traditional HTML parsing can't handle effectively. Large tables that exceed token limits crash extraction processes.
+
+**My Solution:** I developed LLMTableExtraction—an intelligent table extraction strategy that uses Large Language Models with automatic chunking to handle tables of any size and complexity.
+
+### Technical Implementation
+
+```python
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig, 
+    LLMConfig,
+    LLMTableExtraction,
+    CacheMode
+)
+
+# Configure LLM for table extraction
+llm_config = LLMConfig(
+    provider="openai/gpt-4.1-mini",
+    api_token="env:OPENAI_API_KEY",
+    temperature=0.1,  # Low temperature for consistency
+    max_tokens=32000
+)
+
+# Create intelligent table extraction strategy
+table_strategy = LLMTableExtraction(
+    llm_config=llm_config,
+    verbose=True,
+    max_tries=2,
+    enable_chunking=True,           # Handle massive tables
+    chunk_token_threshold=5000,     # Smart chunking threshold
+    overlap_threshold=100,          # Maintain context between chunks
+    extraction_type="structured"    # Get structured data output
+)
+
+# Apply to crawler configuration
+config = CrawlerRunConfig(
+    table_extraction_strategy=table_strategy,
+    cache_mode=CacheMode.BYPASS
+)
+
+async with AsyncWebCrawler() as crawler:
+    # Extract complex tables with intelligence
+    result = await crawler.arun(
+        "https://en.wikipedia.org/wiki/List_of_countries_by_GDP", 
+        config=config
+    )
+    
+    # Access extracted tables directly
+    for i, table in enumerate(result.tables):
+        print(f"Table {i}: {len(table['data'])} rows × {len(table['headers'])} columns")
+        
+        # Convert to pandas DataFrame instantly
+        import pandas as pd
+        df = pd.DataFrame(table['data'], columns=table['headers'])
+        print(df.head())
+```
+
+**Intelligent Chunking for Massive Tables:**
+
+```python
+# Handle tables that exceed token limits
+large_table_strategy = LLMTableExtraction(
+    llm_config=llm_config,
+    enable_chunking=True,
+    chunk_token_threshold=3000,    # Conservative threshold
+    overlap_threshold=150,         # Preserve context
+    max_concurrent_chunks=3,       # Parallel processing
+    merge_strategy="intelligent"   # Smart chunk merging
+)
+
+# Process Wikipedia comparison tables, financial reports, etc.
+config = CrawlerRunConfig(
+    table_extraction_strategy=large_table_strategy,
+    # Target specific table containers
+    css_selector="div.wikitable, table.sortable",
+    delay_before_return_html=2.0
+)
+
+result = await crawler.arun(
+    "https://en.wikipedia.org/wiki/Comparison_of_operating_systems",
+    config=config
+)
+
+# Tables are automatically chunked, processed, and merged
+print(f"Extracted {len(result.tables)} complex tables")
+for table in result.tables:
+    print(f"Merged table: {len(table['data'])} total rows")
+```
+
+**Advanced Features:**
+
+- **Intelligent Chunking**: Automatically splits massive tables while preserving structure
+- **Context Preservation**: Overlapping chunks maintain column relationships
+- **Parallel Processing**: Concurrent chunk processing for speed
+- **Smart Merging**: Reconstructs complete tables from processed chunks
+- **Complex Structure Support**: Handles rowspan, colspan, nested tables
+- **Metadata Extraction**: Captures table context, captions, and relationships
+
+**Expected Real-World Impact:**
+- **Financial Analysis**: Extract complex earnings tables and financial statements
+- **Research & Academia**: Process large datasets from Wikipedia, research papers
+- **E-commerce**: Handle product comparison tables with complex layouts
+- **Government Data**: Extract census data, statistical tables from official sources
+- **Competitive Intelligence**: Process competitor pricing and feature tables
+
+## ⚡ Enhanced Concurrency: True Performance Gains
+
+**The Problem:** The `arun_many()` method wasn't achieving true concurrency for fast-completing tasks, leading to sequential processing bottlenecks in batch operations.
+
+**My Solution:** I implemented true concurrency improvements in the dispatcher that enable genuine parallel processing for fast-completing tasks.
+
+### Performance Optimization
+
+```python
+# Before v0.7.4: Sequential-like behavior for fast tasks
+# After v0.7.4: True concurrency
+
+async with AsyncWebCrawler() as crawler:
+    # These will now run with true concurrency
+    urls = [
+        "https://httpbin.org/delay/1",
+        "https://httpbin.org/delay/1", 
+        "https://httpbin.org/delay/1",
+        "https://httpbin.org/delay/1"
+    ]
+    
+    # Processes in truly parallel fashion
+    results = await crawler.arun_many(urls)
+    
+    # Performance improvement: ~4x faster for fast-completing tasks
+    print(f"Processed {len(results)} URLs with true concurrency")
+```
+
+**Expected Real-World Impact:**
+- **API Crawling**: 3-4x faster processing of REST endpoints and API documentation
+- **Batch URL Processing**: Significant speedup for large URL lists
+- **Monitoring Systems**: Faster health checks and status page monitoring
+- **Data Aggregation**: Improved performance for real-time data collection
+
+## 🧹 Memory Management Refactor: Cleaner Architecture
+
+**The Problem:** Memory utilities were scattered and difficult to maintain, with potential import conflicts and unclear organization.
+
+**My Solution:** I consolidated all memory-related utilities into the main `utils.py` module, creating a cleaner, more maintainable architecture.
+
+### Improved Memory Handling
+
+```python
+# All memory utilities now consolidated
+from crawl4ai.utils import get_true_memory_usage_percent, MemoryMonitor
+
+# Enhanced memory monitoring
+monitor = MemoryMonitor()
+monitor.start_monitoring()
+
+async with AsyncWebCrawler() as crawler:
+    # Memory-efficient batch processing
+    results = await crawler.arun_many(large_url_list)
+    
+    # Get accurate memory metrics
+    memory_usage = get_true_memory_usage_percent()
+    memory_report = monitor.get_report()
+    
+    print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
+    print(f"Peak usage: {memory_report['peak_mb']:.1f} MB")
+```
+
+**Expected Real-World Impact:**
+- **Production Stability**: More reliable memory tracking and management
+- **Code Maintainability**: Cleaner architecture for easier debugging
+- **Import Clarity**: Resolved potential conflicts and import issues
+- **Developer Experience**: Simpler API for memory monitoring
+
+## 🔧 Critical Stability Fixes
+
+### Browser Manager Race Condition Resolution
+
+**The Problem:** Concurrent page creation in persistent browser contexts caused "Target page/context closed" errors during high-concurrency operations.
+
+**My Solution:** Implemented thread-safe page creation with proper locking mechanisms.
+
+```python
+# Fixed: Safe concurrent page creation
+browser_config = BrowserConfig(
+    browser_type="chromium",
+    use_persistent_context=True,  # Now thread-safe
+    max_concurrent_sessions=10    # Safely handle concurrent requests
+)
+
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    # These concurrent operations are now stable
+    tasks = [crawler.arun(url) for url in url_list]
+    results = await asyncio.gather(*tasks)  # No more race conditions
+```
+
+### Enhanced Browser Profiler
+
+**The Problem:** Inconsistent keyboard handling across platforms and unreliable quit mechanisms.
+
+**My Solution:** Cross-platform keyboard listeners with improved quit handling.
+
+### Advanced URL Processing
+
+**The Problem:** Raw URL formats (`raw://` and `raw:`) weren't properly handled, and base tag link resolution was incomplete.
+
+**My Solution:** Enhanced URL preprocessing and base tag support.
+
+```python
+# Now properly handles all URL formats
+urls = [
+    "https://example.com",
+    "raw://static-html-content", 
+    "raw:file://local-file.html"
+]
+
+# Base tag links are now correctly resolved
+config = CrawlerRunConfig(
+    include_links=True,  # Links properly resolved with base tags
+    resolve_absolute_urls=True
+)
+```
+
+## 🛡️ Enhanced Proxy Configuration
+
+**The Problem:** Proxy configuration only accepted specific formats, limiting flexibility.
+
+**My Solution:** Enhanced ProxyConfig to support both dictionary and string formats.
+
+```python
+# Multiple proxy configuration formats now supported
+from crawl4ai import BrowserConfig, ProxyConfig
+
+# String format
+proxy_config = ProxyConfig("http://proxy.example.com:8080")
+
+# Dictionary format  
+proxy_config = ProxyConfig({
+    "server": "http://proxy.example.com:8080",
+    "username": "user",
+    "password": "pass"
+})
+
+# Use with crawler
+browser_config = BrowserConfig(proxy_config=proxy_config)
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    result = await crawler.arun("https://httpbin.org/ip")
+```

-### [Crawl4AI v0.5.0: Deep Crawling, Scalability, and a New CLI!](releases/0.5.0.md)
-
-My dear friends and crawlers, there you go, this is the release of Crawl4AI v0.5.0! This release brings a wealth of new features, performance improvements, and a more streamlined developer experience.  Here's a breakdown of what's new:
-
-**Major New Features:**
-
-*   **Deep Crawling:** Explore entire websites with configurable strategies (BFS, DFS, Best-First).  Define custom filters and URL scoring for targeted crawls.
-*   **Memory-Adaptive Dispatcher:**  Handle large-scale crawls with ease!  Our new dispatcher dynamically adjusts concurrency based on available memory and includes built-in rate limiting.
-*   **Multiple Crawler Strategies:** Choose between the full-featured Playwright browser-based crawler or a new, *much* faster HTTP-only crawler for simpler tasks.
-*   **Docker Deployment:**  Deploy Crawl4AI as a scalable, self-contained service with built-in API endpoints and optional JWT authentication.
-*   **Command-Line Interface (CLI):**  Interact with Crawl4AI directly from your terminal.  Crawl, configure, and extract data with simple commands.
-*   **LLM Configuration (`LLMConfig`):** A new, unified way to configure LLM providers (OpenAI, Anthropic, Ollama, etc.) for extraction, filtering, and schema generation.  Simplifies API key management and switching between models.
-
-**Minor Updates & Improvements:**
-
-*   **LXML Scraping Mode:** Faster HTML parsing with `LXMLWebScrapingStrategy`.
-*   **Proxy Rotation:** Added `ProxyRotationStrategy` with a `RoundRobinProxyStrategy` implementation.
-*   **PDF Processing:** Extract text, images, and metadata from PDF files.
-*   **URL Redirection Tracking:**  Automatically follows and records redirects.
-*   **Robots.txt Compliance:**  Optionally respect website crawling rules.
-*   **LLM-Powered Schema Generation:**  Automatically create extraction schemas using an LLM.
-*   **`LLMContentFilter`:** Generate high-quality, focused markdown using an LLM.
-*   **Improved Error Handling & Stability:** Numerous bug fixes and performance enhancements.
-*   **Enhanced Documentation:**  Updated guides and examples.
-
-**Breaking Changes & Migration:**
-
-This release includes several breaking changes to improve the library's structure and consistency.  Here's what you need to know:
-
-*   **`arun_many()` Behavior:** Now uses the `MemoryAdaptiveDispatcher` by default.  The return type depends on the `stream` parameter in `CrawlerRunConfig`.  Adjust code that relied on unbounded concurrency.
-*   **`max_depth` Location:** Moved to `CrawlerRunConfig` and now controls *crawl depth*.
-*   **Deep Crawling Imports:**  Import `DeepCrawlStrategy` and related classes from `crawl4ai.deep_crawling`.
-*   **`BrowserContext` API:**  Updated; the old `get_context` method is deprecated.
-*   **Optional Model Fields:** Many data model fields are now optional.  Handle potential `None` values.
-*   **`ScrapingMode` Enum:** Replaced with strategy pattern (`WebScrapingStrategy`, `LXMLWebScrapingStrategy`).
-*   **`content_filter` Parameter:** Removed from `CrawlerRunConfig`. Use extraction strategies or markdown generators with filters.
-*   **Removed Functionality:** The synchronous `WebCrawler`, the old CLI, and docs management tools have been removed.
-*   **Docker:**  Significant changes to deployment.  See the [Docker documentation](../deploy/docker/README.md).
-*   **`ssl_certificate.json`:** This file has been removed.
-* **Config**: FastFilterChain has been replaced with FilterChain
-* **Deep-Crawl**: DeepCrawlStrategy.arun now returns Union[CrawlResultT, List[CrawlResultT], AsyncGenerator[CrawlResultT, None]]
-* **Proxy**: Removed synchronous WebCrawler support and related rate limiting configurations
-*   **LLM Parameters:** Use the new `LLMConfig` object instead of passing `provider`, `api_token`, `base_url`, and `api_base` directly to `LLMExtractionStrategy` and `LLMContentFilter`.
-
-**In short:** Update imports, adjust `arun_many()` usage, check for optional fields, and review the Docker deployment guide.
-

+# Table Extraction Strategies
+
+## Overview
+
+**New in v0.7.3+**: Table extraction now follows the **Strategy Design Pattern**, providing unprecedented flexibility and power for handling different table structures. Don't worry - **your existing code still works!** We maintain full backward compatibility while offering new capabilities.
+
+### What's Changed?
+- **Architecture**: Table extraction now uses pluggable strategies
+- **Backward Compatible**: Your existing code with `table_score_threshold` continues to work
+- **More Power**: Choose from multiple strategies or create your own
+- **Same Default Behavior**: By default, uses `DefaultTableExtraction` (same as before)
+
+### Key Points
+✅ **Old code still works** - No breaking changes  
+✅ **Same default behavior** - Uses the proven extraction algorithm  
+✅ **New capabilities** - Add LLM extraction or custom strategies when needed  
+✅ **Strategy pattern** - Clean, extensible architecture
+
+## Quick Start
+
+### The Simplest Way (Works Like Before)
+
+If you're already using Crawl4AI, nothing changes:
+
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+
+async def extract_tables():
+    async with AsyncWebCrawler() as crawler:
+        # This works exactly like before - uses DefaultTableExtraction internally
+        result = await crawler.arun("https://example.com/data")
+        
+        # Tables are automatically extracted and available in result.tables
+        for table in result.tables:
+            print(f"Table with {len(table['rows'])} rows and {len(table['headers'])} columns")
+            print(f"Headers: {table['headers']}")
+            print(f"First row: {table['rows'][0] if table['rows'] else 'No data'}")
+
+asyncio.run(extract_tables())
+```
+
+### Using the Old Configuration (Still Supported)
+
+Your existing code with `table_score_threshold` continues to work:
+
+```python
+# This old approach STILL WORKS - we maintain backward compatibility
+config = CrawlerRunConfig(
+    table_score_threshold=7  # Internally creates DefaultTableExtraction(table_score_threshold=7)
+)
+result = await crawler.arun(url, config)
+```
+
+## Table Extraction Strategies
+
+### Understanding the Strategy Pattern
+
+The strategy pattern allows you to choose different table extraction algorithms at runtime. Think of it as having different tools in a toolbox - you pick the right one for the job:
+
+- **No explicit strategy?** → Uses `DefaultTableExtraction` automatically (same as v0.7.2 and earlier)
+- **Need complex table handling?** → Choose `LLMTableExtraction` (costs money, use sparingly)
+- **Want to disable tables?** → Use `NoTableExtraction`
+- **Have special requirements?** → Create a custom strategy
+
+### Available Strategies
+
+| Strategy | Description | Use Case | Cost | When to Use |
+|----------|-------------|----------|------|-------------|
+| `DefaultTableExtraction` | **RECOMMENDED**: Same algorithm as before v0.7.3 | General purpose (default) | Free | **Use this first - handles 95% of cases** |
+| `LLMTableExtraction` | AI-powered extraction for complex tables | Tables with complex rowspan/colspan | **$$$ Per API call** | Only when DefaultTableExtraction fails |
+| `NoTableExtraction` | Disables table extraction | When tables aren't needed | Free | For text-only extraction |
+| Custom strategies | User-defined extraction logic | Specialized requirements | Free | Domain-specific needs |
+
+> **⚠️ CRITICAL COST WARNING for LLMTableExtraction**: 
+> 
+> **DO NOT USE `LLMTableExtraction` UNLESS ABSOLUTELY NECESSARY!**
+> 
+> - **Always try `DefaultTableExtraction` first** - It's free and handles most tables perfectly
+> - LLM extraction **costs money** with every API call
+> - For large tables (100+ rows), LLM extraction can be **very slow**
+> - **For large tables**: If you must use LLM, choose fast providers:
+>   - ✅ **Groq** (fastest inference)
+>   - ✅ **Cerebras** (optimized for speed)
+>   - ⚠️ Avoid: OpenAI, Anthropic for large tables (slower)
+> 
+> **🚧 WORK IN PROGRESS**: 
+> We are actively developing an **advanced non-LLM algorithm** that will handle complex table structures (rowspan, colspan, nested tables) for **FREE**. This will replace the need for costly LLM extraction in most cases. Coming soon!
+
+### DefaultTableExtraction
+
+The default strategy uses a sophisticated scoring system to identify data tables:
+
+```python
+from crawl4ai import DefaultTableExtraction, CrawlerRunConfig
+
+# Customize the default extraction
+table_strategy = DefaultTableExtraction(
+    table_score_threshold=7,  # Scoring threshold (default: 7)
+    min_rows=2,               # Minimum rows required
+    min_cols=2,               # Minimum columns required
+    verbose=True              # Enable detailed logging
+)
+
+config = CrawlerRunConfig(
+    table_extraction=table_strategy
+)
+```
+
+#### Scoring System
+
+The scoring system evaluates multiple factors:
+
+| Factor | Score Impact | Description |
+|--------|--------------|-------------|
+| Has `<thead>` | +2 | Semantic table structure |
+| Has `<tbody>` | +1 | Organized table body |
+| Has `<th>` elements | +2 | Header cells present |
+| Headers in correct position | +1 | Proper semantic structure |
+| Consistent column count | +2 | Regular data structure |
+| Has caption | +2 | Descriptive caption |
+| Has summary | +1 | Summary attribute |
+| High text density | +2 to +3 | Content-rich cells |
+| Data attributes | +0.5 each | Data-* attributes |
+| Nested tables | -3 | Often indicates layout |
+| Role="presentation" | -3 | Explicitly non-data |
+| Too few rows | -2 | Insufficient data |
+
+### LLMTableExtraction (Use Sparingly!)
+
+**⚠️ WARNING**: Only use this when `DefaultTableExtraction` fails with complex tables!
+
+LLMTableExtraction uses AI to understand complex table structures that traditional parsers struggle with. It automatically handles large tables through intelligent chunking and parallel processing:
+
+```python
+from crawl4ai import LLMTableExtraction, LLMConfig, CrawlerRunConfig
+
+# Configure LLM (costs money per call!)
+llm_config = LLMConfig(
+    provider="groq/llama-3.3-70b-versatile",  # Fast provider for large tables
+    api_token="your_api_key",
+    temperature=0.1
+)
+
+# Create LLM extraction strategy with smart chunking
+table_strategy = LLMTableExtraction(
+    llm_config=llm_config,
+    max_tries=3,                      # Retry up to 3 times if extraction fails
+    css_selector="table",             # Optional: focus on specific tables
+    enable_chunking=True,             # Automatically chunk large tables (default: True)
+    chunk_token_threshold=3000,       # Split tables larger than this (default: 3000 tokens)
+    min_rows_per_chunk=10,            # Minimum rows per chunk (default: 10)
+    max_parallel_chunks=5,            # Process up to 5 chunks in parallel (default: 5)
+    verbose=True
+)
+
+config = CrawlerRunConfig(
+    table_extraction=table_strategy
+)
+
+result = await crawler.arun(url, config)
+```
+
+#### When to Use LLMTableExtraction
+
+✅ **Use ONLY when**:
+- Tables have complex merged cells (rowspan/colspan) that break DefaultTableExtraction
+- Nested tables that need semantic understanding
+- Tables with irregular structures
+- You've tried DefaultTableExtraction and it failed
+
+❌ **Never use when**:
+- DefaultTableExtraction works (99% of cases)
+- Tables are simple or well-structured
+- You're processing many pages (costs add up!)
+- Tables have 100+ rows (very slow)
+
+#### How Smart Chunking Works
+
+LLMTableExtraction automatically handles large tables through intelligent chunking:
+
+1. **Automatic Detection**: Tables exceeding the token threshold are automatically split
+2. **Smart Splitting**: Chunks are created at row boundaries, preserving table structure
+3. **Header Preservation**: Each chunk includes the original headers for context
+4. **Parallel Processing**: Multiple chunks are processed simultaneously for speed
+5. **Intelligent Merging**: Results are merged back into a single, complete table
+
+**Chunking Parameters**:
+- `enable_chunking` (default: `True`): Automatically handle large tables
+- `chunk_token_threshold` (default: `3000`): When to split tables
+- `min_rows_per_chunk` (default: `10`): Ensures meaningful chunk sizes
+- `max_parallel_chunks` (default: `5`): Concurrent processing for speed
+
+The chunking is completely transparent - you get the same output format whether the table was processed in one piece or multiple chunks.
+
+#### Performance Optimization for LLMTableExtraction
+
+**Provider Recommendations by Table Size**:
+
+| Table Size | Recommended Providers | Why |
+|------------|----------------------|-----|
+| Small (<50 rows) | Any provider | Fast enough |
+| Medium (50-200 rows) | Groq, Cerebras | Optimized inference |
+| Large (200+ rows) | **Groq** (best), Cerebras | Fastest inference + automatic chunking |
+| Very Large (500+ rows) | Groq with chunking | Parallel processing keeps it fast |
+
+### NoTableExtraction
+
+Disable table extraction for better performance when tables aren't needed:
+
+```python
+from crawl4ai import NoTableExtraction, CrawlerRunConfig
+
+config = CrawlerRunConfig(
+    table_extraction=NoTableExtraction()
+)
+
+# Tables won't be extracted, improving performance
+result = await crawler.arun(url, config)
+assert len(result.tables) == 0
+```
+
+## Extracted Table Structure
+
+Each extracted table contains:
+
+```python
+{
+    "headers": ["Column 1", "Column 2", ...],  # Column headers
+    "rows": [                                   # Data rows
+        ["Row 1 Col 1", "Row 1 Col 2", ...],
+        ["Row 2 Col 1", "Row 2 Col 2", ...],
+    ],
+    "caption": "Table Caption",                # If present
+    "summary": "Table Summary",                # If present
+    "metadata": {
+        "row_count": 10,                       # Number of rows
+        "column_count": 3,                      # Number of columns
+        "has_headers": True,                    # Headers detected
+        "has_caption": True,                    # Caption exists
+        "has_summary": False,                   # Summary exists
+        "id": "data-table-1",                   # Table ID if present
+        "class": "financial-data"               # Table class if present
+    }
+}
+```
+
+## Configuration Options
+
+### Basic Configuration
+
+```python
+config = CrawlerRunConfig(
+    # Table extraction settings
+    table_score_threshold=7,      # Default threshold (backward compatible)
+    table_extraction=strategy,     # Optional: custom strategy
+    
+    # Filter what to process
+    css_selector="main",          # Focus on specific area
+    excluded_tags=["nav", "aside"] # Exclude page sections
+)
+```
+
+### Advanced Configuration
+
+```python
+from crawl4ai import DefaultTableExtraction, CrawlerRunConfig
+
+# Fine-tuned extraction
+strategy = DefaultTableExtraction(

+
+## Working with Extracted Tables
+
+### Convert to Pandas DataFrame
+
+```python
+import pandas as pd
+
+async def tables_to_dataframes(url):
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(url)
+        
+        dataframes = []
+        for table_data in result.tables:
+            # Create DataFrame
+            if table_data['headers']:
+                df = pd.DataFrame(
+                    table_data['rows'],
+                    columns=table_data['headers']
+                )
+            else:
+                df = pd.DataFrame(table_data['rows'])
+            
+            # Add metadata as DataFrame attributes

+            df.attrs['metadata'] = table_data.get('metadata', {})
+            
+            dataframes.append(df)
+        
+        return dataframes
+```
+
+### Filter Tables by Criteria
+
+```python
+async def extract_large_tables(url):
+    async with AsyncWebCrawler() as crawler:
+        # Configure minimum size requirements
+        strategy = DefaultTableExtraction(
+            min_rows=10,
+            min_cols=3,
+            table_score_threshold=6
+        )
+        
+        config = CrawlerRunConfig(
+            table_extraction=strategy
+        )
+        
+        result = await crawler.arun(url, config)
+        
+        # Further filter results
+        large_tables = [
+            table for table in result.tables
+            if table['metadata']['row_count'] > 10
+            and table['metadata']['column_count'] > 3
+        ]
+        
+        return large_tables
+```
+
+### Export Tables to Different Formats
+
+```python
+import json
+import csv
+
+async def export_tables(url):
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(url)
+

+            # Export as JSON
+            with open(f'table_{i}.json', 'w') as f:
+                json.dump(table, f, indent=2)
+            
+            # Export as CSV
+            with open(f'table_{i}.csv', 'w', newline='') as f:
+                writer = csv.writer(f)
+                if table['headers']:
+                    writer.writerow(table['headers'])
+                writer.writerows(table['rows'])

+            # Export as Markdown
+            with open(f'table_{i}.md', 'w') as f:
+                # Write headers
+                if table['headers']:
+                    f.write('| ' + ' | '.join(table['headers']) + ' |\n')
+                    f.write('|' + '---|' * len(table['headers']) + '\n')
+                
+                # Write rows
+                for row in table['rows']:
+                    f.write('| ' + ' | '.join(str(cell) for cell in row) + ' |\n')
+```
+
+## Creating Custom Strategies
+
+Extend `TableExtractionStrategy` to create custom extraction logic:
+
+### Example: Financial Table Extractor
+
+```python
+from crawl4ai import TableExtractionStrategy
+from typing import List, Dict, Any
+import re
+
+class FinancialTableExtractor(TableExtractionStrategy):
+    """Extract tables containing financial data."""
+    
+    def __init__(self, currency_symbols=None, require_numbers=True, **kwargs):
+        super().__init__(**kwargs)
+        self.currency_symbols = currency_symbols or ['$', '€', '£', '¥']
+        self.require_numbers = require_numbers
+        self.number_pattern = re.compile(r'\d+[,.]?\d*')
+    
+    def extract_tables(self, element, **kwargs):
+        tables_data = []
+        
+        for table in element.xpath(".//table"):
+            # Check if table contains financial indicators
+            table_text = ''.join(table.itertext())
+            
+            # Must contain currency symbols
+            has_currency = any(sym in table_text for sym in self.currency_symbols)
+            if not has_currency:

+                if len(numbers) < 3:  # Arbitrary minimum
+                    continue
+

+    
+    def _get_caption(self, table):

+
+# Usage
+strategy = FinancialTableExtractor(
+    currency_symbols=['$', 'EUR'],
+    require_numbers=True
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### Example: Specific Table Extractor
+
+```python

+        
+        return tables_data
+```
+
+## Combining with Other Strategies
+
+Table extraction works seamlessly with other Crawl4AI strategies:
+
+```python
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig,
+    DefaultTableExtraction,
+    LLMExtractionStrategy,
+    JsonCssExtractionStrategy
+)
+
+async def combined_extraction(url):
+    async with AsyncWebCrawler() as crawler:
+        config = CrawlerRunConfig(
+            # Table extraction
+            table_extraction=DefaultTableExtraction(
+                table_score_threshold=6,
+                min_rows=2
+            ),
+            
+            # CSS-based extraction for specific elements
+            extraction_strategy=JsonCssExtractionStrategy({
+                "title": "h1",
+                "summary": "p.summary",
+                "date": "time"
+            }),
+            
+            # Focus on main content
+            css_selector="main.content"
+        )
+        
+        result = await crawler.arun(url, config)
+        
+        # Access different extraction results
+        tables = result.tables  # Table data
+        structured = json.loads(result.extracted_content)  # CSS extraction
+        
+        return {
+            "tables": tables,
+            "structured_data": structured,
+            "markdown": result.markdown
+        }
+```
+
+## Performance Considerations
+
+### Optimization Tips
+
+1. **Disable when not needed**: Use `NoTableExtraction` if tables aren't required
+2. **Target specific areas**: Use `css_selector` to limit processing scope
+3. **Set minimum thresholds**: Filter out small/irrelevant tables early
+4. **Cache results**: Use appropriate cache modes for repeated extractions
+
+```python
+# Optimized configuration for large pages
+config = CrawlerRunConfig(
+    # Only process main content area
+    css_selector="article.main-content",
+    
+    # Exclude navigation and sidebars
+    excluded_tags=["nav", "aside", "footer"],
+    
+    # Higher threshold for stricter filtering
+    table_extraction=DefaultTableExtraction(
+        table_score_threshold=8,
+        min_rows=5,
+        min_cols=3
+    ),
+    
+    # Enable caching for repeated access
+    cache_mode=CacheMode.ENABLED
+)
+```
+
+## Migration Guide
+
+### Important: Your Code Still Works!
+
+**No changes required!** The transition to the strategy pattern is **fully backward compatible**.
+
+### How It Works Internally
+
+#### v0.7.2 and Earlier
+```python
+# Old way - directly passing table_score_threshold
+config = CrawlerRunConfig(
+    table_score_threshold=7
+)
+# Internally: No strategy pattern, direct implementation
+```
+
+#### v0.7.3+ (Current)
+```python
+# Old way STILL WORKS - we handle it internally
+config = CrawlerRunConfig(
+    table_score_threshold=7
+)
+# Internally: Automatically creates DefaultTableExtraction(table_score_threshold=7)
+```
+
+### Taking Advantage of New Features
+
+While your old code works, you can now use the strategy pattern for more control:
+
+```python
+# Option 1: Keep using the old way (perfectly fine!)
+config = CrawlerRunConfig(
+    table_score_threshold=7  # Still supported
+)
+
+# Option 2: Use the new strategy pattern (more flexibility)
+from crawl4ai import DefaultTableExtraction
+
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,
+    min_rows=2,  # New capability!
+    min_cols=2   # New capability!
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+
+# Option 3: Use advanced strategies when needed
+from crawl4ai import LLMTableExtraction, LLMConfig
+
+# Only for complex tables that DefaultTableExtraction can't handle
+# Automatically handles large tables with smart chunking
+llm_strategy = LLMTableExtraction(
+    llm_config=LLMConfig(
+        provider="groq/llama-3.3-70b-versatile",
+        api_token="your_key"
+    ),
+    max_tries=3,
+    enable_chunking=True,  # Automatically chunk large tables
+    chunk_token_threshold=3000,  # Chunk when exceeding 3000 tokens
+    max_parallel_chunks=5  # Process up to 5 chunks in parallel
+)
+
+config = CrawlerRunConfig(
+    table_extraction=llm_strategy  # Advanced extraction with automatic chunking
+)
+```
+
+### Summary
+
+- ✅ **No breaking changes** - Old code works as-is
+- ✅ **Same defaults** - DefaultTableExtraction is automatically used
+- ✅ **Gradual adoption** - Use new features when you need them
+- ✅ **Full compatibility** - result.tables structure unchanged
+
+## Best Practices
+
+### 1. Choose the Right Strategy (Cost-Conscious Approach)
+
+**Decision Flow**:
+```
+1. Do you need tables? 
+   → No: Use NoTableExtraction
+   → Yes: Continue to #2
+
+2. Try DefaultTableExtraction first (FREE)
+   → Works? Done! ✅
+   → Fails? Continue to #3
+
+3. Is the table critical and complex?
+   → No: Accept DefaultTableExtraction results
+   → Yes: Continue to #4
+
+4. Use LLMTableExtraction (COSTS MONEY)
+   → Small table (<50 rows): Any LLM provider
+   → Large table (50+ rows): Use Groq or Cerebras
+   → Very large (500+ rows): Reconsider - maybe chunk the page
+```
+
+**Strategy Selection Guide**:
+- **DefaultTableExtraction**: Use for 99% of cases - it's free and effective
+- **LLMTableExtraction**: Only for complex tables with merged cells that break DefaultTableExtraction
+- **NoTableExtraction**: When you only need text/markdown content
+- **Custom Strategy**: For specialized requirements (financial, scientific, etc.)
+
+### 2. Validate Extracted Data
+
+```python
+def validate_table(table):
+    """Validate table data quality."""
+    # Check structure
+    if not table.get('rows'):
+        return False
+    
+    # Check consistency
+    if table.get('headers'):
+        expected_cols = len(table['headers'])
+        for row in table['rows']:
+            if len(row) != expected_cols:
+                return False
+    
+    # Check minimum content
+    total_cells = sum(len(row) for row in table['rows'])
+    non_empty = sum(1 for row in table['rows'] 
+                    for cell in row if cell.strip())
+    
+    if non_empty / total_cells < 0.5:  # Less than 50% non-empty
+        return False
+    
+    return True
+
+# Filter valid tables
+valid_tables = [t for t in result.tables if validate_table(t)]
+```
+
+### 3. Handle Edge Cases
+
+```python
+async def robust_table_extraction(url):
+    """Extract tables with error handling."""
+    async with AsyncWebCrawler() as crawler:
+        try:
+            config = CrawlerRunConfig(
+                table_extraction=DefaultTableExtraction(
+                    table_score_threshold=6,
+                    verbose=True
+                )
+            )
+            
+            result = await crawler.arun(url, config)
+            
+            if not result.success:
+                print(f"Crawl failed: {result.error}")
+                return []
+            
+            # Process tables safely
+            processed_tables = []
+            for table in result.tables:
+                try:
+                    # Validate and process
+                    if validate_table(table):
+                        processed_tables.append(table)
+                except Exception as e:
+                    print(f"Error processing table: {e}")
+                    continue
+            
+            return processed_tables
+            
+        except Exception as e:
+            print(f"Extraction error: {e}")
+            return []
+```
+
+## Troubleshooting
+
+### Common Issues and Solutions
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| No tables extracted | Score too high | Lower `table_score_threshold` |
+| Layout tables included | Score too low | Increase `table_score_threshold` |
+| Missing tables | CSS selector too specific | Broaden or remove `css_selector` |
+| Incomplete data | Complex table structure | Create custom strategy |
+| Performance issues | Processing entire page | Use `css_selector` to limit scope |
+
+### Debug Logging
+
+Enable verbose logging to understand extraction decisions:
+
+```python
+import logging
+
+# Configure logging
+logging.basicConfig(level=logging.DEBUG)
+
+# Enable verbose mode in strategy
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,
+    verbose=True  # Detailed extraction logs
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy,
+    verbose=True  # General crawler logs
+)
+```

+# Telemetry
+
+Crawl4AI includes **opt-in telemetry** to help improve stability by capturing anonymous crash reports. No personal data or crawled content is ever collected.
+
+!!! info "Privacy First"
+    Telemetry is completely optional and respects your privacy. Only exception information is collected - no URLs, no personal data, no crawled content.
+
+## Overview
+
+- **Privacy-first**: Only exceptions and crashes are reported
+- **Opt-in by default**: You control when telemetry is enabled (except in Docker where it's on by default)
+- **No PII**: No URLs, request data, or personal information is collected
+- **Provider-agnostic**: Currently uses Sentry, but designed to support multiple backends
+
+## Installation
+
+Telemetry requires the optional Sentry SDK:
+
+```bash
+# Install with telemetry support
+pip install crawl4ai[telemetry]
+
+# Or install Sentry SDK separately
+pip install sentry-sdk>=2.0.0
+```
+
+## Environments
+
+### 1. Python Library & CLI
+
+On first exception, you'll see an interactive prompt:
+
+```
+🚨 Crawl4AI Error Detection

+crwl telemetry enable --email you@example.com
+
+# Disable telemetry
+crwl telemetry disable
+
+# Check status
+crwl telemetry status
+```
+
+### 2. Docker / API Server
+
+!!! warning "Default Enabled in Docker"
+    Telemetry is **enabled by default** in Docker environments to help identify container-specific issues. This is different from the CLI where it's opt-in.
+
+To disable:
+```bash
+# Via environment variable
+docker run -e CRAWL4AI_TELEMETRY=0 ...
+
+# In docker-compose.yml
+environment:
+  - CRAWL4AI_TELEMETRY=0
+```
+
+### 3. Jupyter / Google Colab
+
+In notebooks, you'll see an interactive widget (if available) or a code snippet:
+
+```python
+import crawl4ai
+
+# Enable telemetry
+crawl4ai.telemetry.enable(email="you@example.com", always=True)
+
+# Send only next error
+crawl4ai.telemetry.enable(once=True)
+
+# Disable telemetry
+crawl4ai.telemetry.disable()
+
+# Check status
+crawl4ai.telemetry.status()
+```
+
+## Python API
+
+### Basic Usage
+
+```python
+from crawl4ai import telemetry
+
+# Enable/disable telemetry
+telemetry.enable(email="optional@email.com", always=True)
+telemetry.disable()
+
+# Check current status
+status = telemetry.status()
+print(f"Telemetry enabled: {status['enabled']}")
+print(f"Consent: {status['consent']}")
+```
+
+### Manual Exception Capture
+
+```python
+from crawl4ai.telemetry import capture_exception
+
+try:
+    # Your code here
+    risky_operation()
+except Exception as e:
+    # Manually capture exception with context
+    capture_exception(e, {
+        'operation': 'custom_crawler',
+        'url': 'https://example.com'  # Will be sanitized
+    })
+    raise
+```
+
+### Decorator Pattern
+
+```python
+from crawl4ai.telemetry import telemetry_decorator
+
+@telemetry_decorator
+def my_crawler_function():
+    # Exceptions will be automatically captured
+    pass
+```
+
+### Context Manager
+
+```python
+from crawl4ai.telemetry import telemetry_context
+
+with telemetry_context("data_extraction"):
+    # Any exceptions in this block will be captured
+    result = extract_data(html)
+```
+
+## Configuration
+
+Settings are stored in `~/.crawl4ai/config.json`:
+
+```json
+{
+  "telemetry": {
+    "consent": "always",
+    "email": "user@example.com"
+  }
+}
+```
+
+Consent levels:
+- `"not_set"` - No decision made yet
+- `"denied"` - Telemetry disabled
+- `"once"` - Send current error only
+- `"always"` - Always send errors
+
+## Environment Variables
+
+- `CRAWL4AI_TELEMETRY=0` - Disable telemetry (overrides config)
+- `CRAWL4AI_TELEMETRY_EMAIL=email@example.com` - Set email for follow-up
+- `CRAWL4AI_SENTRY_DSN=https://...` - Override default DSN (for maintainers)
+
+## What's Collected
+
+### Collected ✅
+- Exception type and traceback
+- Crawl4AI version
+- Python version
+- Operating system
+- Environment type (CLI, Docker, Jupyter)
+- Optional email (if provided)
+
+### NOT Collected ❌
+- URLs being crawled
+- HTML content
+- Request/response data
+- Cookies or authentication tokens
+- IP addresses
+- Any personally identifiable information
+
+## Provider Architecture
+
+Telemetry is designed to be provider-agnostic:
+
+```python
+from crawl4ai.telemetry.base import TelemetryProvider
+
+class CustomProvider(TelemetryProvider):
+    def send_exception(self, exc, context=None):
+        # Your implementation
+        pass
+```
+
+## FAQ
+
+### Q: Can I completely disable telemetry?
+A: Yes! Use `crwl telemetry disable` or set `CRAWL4AI_TELEMETRY=0`
+
+### Q: Is telemetry required?
+A: No, it's completely optional (except enabled by default in Docker)
+
+### Q: What if I don't install sentry-sdk?
+A: Telemetry will gracefully degrade to a no-op state
+
+### Q: Can I see what's being sent?
+A: Yes, check the source code in `crawl4ai/telemetry/`
+
+### Q: How do I remove my email?
+A: Delete `~/.crawl4ai/config.json` or edit it to remove the email field
+
+## Privacy Commitment
+
+1. **Transparency**: All telemetry code is open source
+2. **Control**: You can enable/disable at any time
+3. **Minimal**: Only crash data, no user content
+4. **Secure**: Data transmitted over HTTPS to Sentry
+5. **Anonymous**: No tracking or user identification
+
+## Contributing
+
+Help improve telemetry:
+- Report issues with telemetry itself
+- Suggest privacy improvements
+- Add new provider backends
+
+## Support
+
+If you have concerns about telemetry:
+- Open an issue on GitHub
+- Email the maintainers
+- Review the code in `crawl4ai/telemetry/`

+# Migration Guide: Table Extraction v0.7.3
+
+## Overview
+
+Version 0.7.3 introduces the **Table Extraction Strategy Pattern**, providing a more flexible and extensible approach to table extraction while maintaining full backward compatibility.
+
+## What's New
+
+### Strategy Pattern Implementation
+
+Table extraction now follows the same strategy pattern used throughout Crawl4AI:
+
+- **Consistent Architecture**: Aligns with extraction, chunking, and markdown strategies
+- **Extensibility**: Easy to create custom table extraction strategies
+- **Better Separation**: Table logic moved from content scraping to dedicated module
+- **Full Control**: Fine-grained control over table detection and extraction
+
+### New Classes
+
+```python
+from crawl4ai import (
+    TableExtractionStrategy,    # Abstract base class
+    DefaultTableExtraction,      # Current implementation (default)
+    NoTableExtraction           # Explicitly disable extraction
+)
+```
+
+## Backward Compatibility
+
+**✅ All existing code continues to work without changes.**
+
+### No Changes Required
+
+If your code looks like this, it will continue to work:
+
+```python
+# This still works exactly the same
+config = CrawlerRunConfig(
+    table_score_threshold=7
+)
+result = await crawler.arun(url, config)
+tables = result.tables  # Same structure, same data
+```
+
+### What Happens Behind the Scenes
+
+When you don't specify a `table_extraction` strategy:
+
+1. `CrawlerRunConfig` automatically creates `DefaultTableExtraction`
+2. It uses your `table_score_threshold` parameter
+3. Tables are extracted exactly as before
+4. Results appear in `result.tables` with the same structure
+
+## New Capabilities
+
+### 1. Explicit Strategy Configuration
+
+You can now explicitly configure table extraction:
+
+```python
+# New: Explicit control
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,
+    min_rows=2,              # New: minimum row filter
+    min_cols=2,              # New: minimum column filter
+    verbose=True             # New: detailed logging
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### 2. Disable Table Extraction
+
+Improve performance when tables aren't needed:
+
+```python
+# New: Skip table extraction entirely
+config = CrawlerRunConfig(
+    table_extraction=NoTableExtraction()
+)
+# No CPU cycles spent on table detection/extraction
+```
+
+### 3. Custom Extraction Strategies
+
+Create specialized extractors:
+
+```python
+class MyTableExtractor(TableExtractionStrategy):
+    def extract_tables(self, element, **kwargs):
+        # Custom extraction logic
+        return custom_tables
+
+config = CrawlerRunConfig(
+    table_extraction=MyTableExtractor()
+)
+```
+
+## Migration Scenarios
+
+### Scenario 1: Basic Usage (No Changes Needed)
+
+**Before (v0.7.2):**
+```python
+config = CrawlerRunConfig()
+result = await crawler.arun(url, config)
+for table in result.tables:
+    print(table['headers'])
+```
+
+**After (v0.7.3):**
+```python
+# Exactly the same - no changes required
+config = CrawlerRunConfig()
+result = await crawler.arun(url, config)
+for table in result.tables:
+    print(table['headers'])
+```
+
+### Scenario 2: Custom Threshold (No Changes Needed)
+
+**Before (v0.7.2):**
+```python
+config = CrawlerRunConfig(
+    table_score_threshold=5
+)
+```
+
+**After (v0.7.3):**
+```python
+# Still works the same
+config = CrawlerRunConfig(
+    table_score_threshold=5
+)
+
+# Or use new explicit approach for more control
+strategy = DefaultTableExtraction(
+    table_score_threshold=5,
+    min_rows=2  # Additional filtering
+)
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### Scenario 3: Advanced Filtering (New Feature)
+
+**Before (v0.7.2):**
+```python
+# Had to filter after extraction
+config = CrawlerRunConfig(
+    table_score_threshold=5
+)
+result = await crawler.arun(url, config)
+
+# Manual filtering
+large_tables = [
+    t for t in result.tables 
+    if len(t['rows']) >= 5 and len(t['headers']) >= 3
+]
+```
+
+**After (v0.7.3):**
+```python
+# Filter during extraction (more efficient)
+strategy = DefaultTableExtraction(
+    table_score_threshold=5,
+    min_rows=5,
+    min_cols=3
+)
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+result = await crawler.arun(url, config)
+# result.tables already filtered
+```
+
+## Code Organization Changes
+
+### Module Structure
+
+**Before (v0.7.2):**
+```
+crawl4ai/
+  content_scraping_strategy.py
+    - LXMLWebScrapingStrategy
+      - is_data_table()      # Table detection
+      - extract_table_data() # Table extraction
+```
+
+**After (v0.7.3):**
+```
+crawl4ai/
+  content_scraping_strategy.py
+    - LXMLWebScrapingStrategy
+      # Table methods removed, uses strategy
+  
+  table_extraction.py (NEW)
+    - TableExtractionStrategy    # Base class
+    - DefaultTableExtraction      # Moved logic here
+    - NoTableExtraction          # New option
+```
+
+### Import Changes
+
+**New imports available (optional):**
+```python
+# These are now available but not required for existing code
+from crawl4ai import (
+    TableExtractionStrategy,
+    DefaultTableExtraction,
+    NoTableExtraction
+)
+```
+
+## Performance Implications
+
+### No Performance Impact
+
+For existing code, performance remains identical:
+- Same extraction logic
+- Same scoring algorithm
+- Same processing time
+
+### Performance Improvements Available
+
+New options for better performance:
+
+```python
+# Skip tables entirely (faster)
+config = CrawlerRunConfig(
+    table_extraction=NoTableExtraction()
+)
+
+# Process only specific areas (faster)
+config = CrawlerRunConfig(
+    css_selector="main.content",
+    table_extraction=DefaultTableExtraction(
+        min_rows=5,  # Skip small tables
+        min_cols=3
+    )
+)
+```
+
+## Testing Your Migration
+
+### Verification Script
+
+Run this to verify your extraction still works:
+
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+
+async def verify_extraction():
+    url = "your_url_here"
+    
+    async with AsyncWebCrawler() as crawler:
+        # Test 1: Old approach
+        config_old = CrawlerRunConfig(
+            table_score_threshold=7
+        )
+        result_old = await crawler.arun(url, config_old)
+        
+        # Test 2: New explicit approach
+        from crawl4ai import DefaultTableExtraction
+        config_new = CrawlerRunConfig(
+            table_extraction=DefaultTableExtraction(
+                table_score_threshold=7
+            )
+        )
+        result_new = await crawler.arun(url, config_new)
+        
+        # Compare results
+        assert len(result_old.tables) == len(result_new.tables)
+        print(f"✓ Both approaches extracted {len(result_old.tables)} tables")
+        
+        # Verify structure
+        for old, new in zip(result_old.tables, result_new.tables):
+            assert old['headers'] == new['headers']
+            assert old['rows'] == new['rows']
+        
+        print("✓ Table content identical")
+
+asyncio.run(verify_extraction())
+```
+
+## Deprecation Notes
+
+### No Deprecations
+
+- All existing parameters continue to work
+- `table_score_threshold` in `CrawlerRunConfig` is still supported
+- No breaking changes
+
+### Internal Changes (Transparent to Users)
+
+- `LXMLWebScrapingStrategy.is_data_table()` - Moved to `DefaultTableExtraction`
+- `LXMLWebScrapingStrategy.extract_table_data()` - Moved to `DefaultTableExtraction`
+
+These methods were internal and not part of the public API.
+
+## Benefits of Upgrading
+
+While not required, using the new pattern provides:
+
+1. **Better Control**: Filter tables during extraction, not after
+2. **Performance Options**: Skip extraction when not needed
+3. **Extensibility**: Create custom extractors for specific needs
+4. **Consistency**: Same pattern as other Crawl4AI strategies
+5. **Future-Proof**: Ready for upcoming advanced strategies
+
+## Troubleshooting
+
+### Issue: Different Number of Tables
+
+**Cause**: Threshold or filtering differences
+
+**Solution**: 
+```python
+# Ensure same threshold
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,  # Match your old setting
+    min_rows=0,               # No filtering (default)
+    min_cols=0                # No filtering (default)
+)
+```
+
+### Issue: Import Errors
+
+**Cause**: Using new classes without importing
+
+**Solution**:
+```python
+# Add imports if using new features
+from crawl4ai import (
+    DefaultTableExtraction,
+    NoTableExtraction,
+    TableExtractionStrategy
+)
+```
+
+### Issue: Custom Strategy Not Working
+
+**Cause**: Incorrect method signature
+
+**Solution**:
+```python
+class CustomExtractor(TableExtractionStrategy):
+    def extract_tables(self, element, **kwargs):  # Correct signature
+        # Not: extract_tables(self, html)
+        # Not: extract(self, element)
+        return tables_list
+```
+
+## Getting Help
+
+If you encounter issues:
+
+1. Check your `table_score_threshold` matches previous settings
+2. Verify imports if using new classes
+3. Enable verbose logging: `DefaultTableExtraction(verbose=True)`
+4. Review the [Table Extraction Documentation](../core/table_extraction.md)
+5. Check [examples](../examples/table_extraction_example.py)
+
+## Summary
+
+- ✅ **Full backward compatibility** - No code changes required
+- ✅ **Same results** - Identical extraction behavior by default
+- ✅ **New options** - Additional control when needed
+- ✅ **Better architecture** - Consistent with Crawl4AI patterns
+- ✅ **Ready for future** - Foundation for advanced strategies
+
+The migration to v0.7.3 is seamless with no required changes while providing new capabilities for those who need them.
