Subject: [PATCH 1/6] fix(browser_profiler): cross-platform 'q' to quit

This commit introduces platform-specific handling for the 'q' key press to quit the browser profiler, ensuring compatibility with both Windows and Unix-like systems. It also adds a check to see if the browser process has already exited, terminating the input listener if so.

- Implemented `msvcrt` for Windows to capture keyboard input without requiring a newline.
- Retained `termios`, `tty`, and `select` for Unix-like systems.
- Added a check for browser process termination to gracefully exit the input listener.
- Updated logger messages to use colored output for better user experience.

Subject: [PATCH 2/6] fix(browser_profiler): improve keyboard input handling

- fix handling of special keys in Windows msvcrt implementation
- Guard against UnicodeDecodeError from multi-byte key sequences
- Filter out non-printable characters and control sequences
- Add error handling to prevent coroutine crashes
- Add unit test to verify keyboard input handling

Key changes:
- Safe UTF-8 decoding with try/except for special keys
- Skip non-printable and multi-byte character sequences
- Add broad exception handling in keyboard listener

Test runs on Windows only due to msvcrt dependency.

BREAKING CHANGE: Table extraction now uses Strategy Design Pattern

This epic commit introduces a game-changing approach to table extraction in Crawl4AI:

✨ NEW FEATURES:
- LLMTableExtraction: AI-powered extraction for complex HTML tables with rowspan/colspan
- Smart Chunking: Automatically splits massive tables into optimal chunks at row boundaries
- Parallel Processing: Processes multiple chunks simultaneously for blazing-fast extraction
- Intelligent Merging: Seamlessly combines chunk results into complete tables
- Header Preservation: Each chunk maintains context with original headers
- Auto-retry Logic: Built-in resilience with configurable retry attempts

🏗️ ARCHITECTURE:
- Strategy Design Pattern for pluggable table extraction strategies
- ThreadPoolExecutor for concurrent chunk processing
- Token-based chunking with configurable thresholds
- Handles tables without headers gracefully

⚡ PERFORMANCE:
- Process 1000+ row tables without timeout
- Parallel processing with up to 5 concurrent chunks
- Smart token estimation prevents LLM context overflow
- Optimized for providers like Groq for massive tables

🔧 CONFIGURATION:
- enable_chunking: Auto-handle large tables (default: True)
- chunk_token_threshold: When to split (default: 3000 tokens)
- min_rows_per_chunk: Meaningful chunk sizes (default: 10)
- max_parallel_chunks: Concurrent processing (default: 5)

📚 BACKWARD COMPATIBILITY:
- Existing code continues to work unchanged
- DefaultTableExtraction remains the default strategy
- Progressive enhancement approach

This is the future of web table extraction - handling everything from simple tables to massive, complex data grids with merged cells and nested structures. The chunking is completely transparent to users while providing unprecedented scalability.

+    # System prompt for table extraction
+    TABLE_EXTRACTION_PROMPT = """You are a specialized table extraction system that converts complex HTML tables into structured JSON data. Your primary goal is to handle difficult, irregular HTML tables that cannot be easily parsed by standard tools, transforming them into clean, tabulated data.
+
+## Critical Requirements
+
+**IMPORTANT**: You must extract **EVERY SINGLE ROW** from the table, regardless of size. Tables often contain hundreds of rows, and omitting data is unacceptable. The reason we use an LLM for this task is because these tables have complex structures that standard parsers cannot handle properly.
+
+## Output Format
+
+**Your response must be valid JSON**. The output must be properly formatted, parseable JSON with:
+- Proper escaping of quotes in strings
+- Valid JSON syntax (commas, brackets, etc.)
+- No trailing commas
+- Proper handling of special characters
+
+## Table Structure
+
+Every table should be extracted as a JSON object with this structure:
+
+```json
+{
+    "headers": ["Column 1", "Column 2", ...],
+    "rows": [
+        ["Row 1 Col 1", "Row 1 Col 2", ...],
+        ["Row 2 Col 1", "Row 2 Col 2", ...],
+        // ... continue for ALL rows ...
+    ],
+    "caption": "Table caption if present",
+    "summary": "Table summary attribute if present",
+    "metadata": {
+        "row_count": <actual_number_of_rows>,
+        "column_count": <number>,
+        "has_headers": <boolean>,
+        "has_merged_cells": <boolean>,
+        "nested_tables": <boolean>,
+        "table_type": "data|pivot|matrix|nested"
+    }
+}
+```
+
+## Handling Complex Structures
+
+### Why This Matters
+Standard HTML parsers fail on tables with:
+- Complex colspan/rowspan arrangements
+- Nested tables
+- Irregular structures
+- Mixed header patterns
+
+Your job is to intelligently interpret these structures and produce clean, regular data.
+
+### Colspan (Merged Columns)
+When a cell spans multiple columns, duplicate the value across all spanned columns to maintain rectangular data structure.
+
+Example HTML:
+```html
+<tr>
+    <td colspan="3">Quarterly Report</td>
+    <td>Total</td>
+</tr>
+```
+Becomes: ["Quarterly Report", "Quarterly Report", "Quarterly Report", "Total"]
+
+### Rowspan (Merged Rows)
+When a cell spans multiple rows, duplicate the value down all affected rows.
+
+Example with many rows:
+```html
+<tr>
+    <td rowspan="50">Category A</td>
+    <td>Item 1</td>
+    <td>$100</td>
+</tr>
+<tr>
+    <td>Item 2</td>
+    <td>$200</td>
+</tr>
+<!-- ... 48 more rows ... -->
+```
+
+Result structure (response must be valid JSON):
+```json
+{
+    "headers": ["Category", "Item", "Price"],
+    "rows": [
+        ["Category A", "Item 1", "$100"],
+        ["Category A", "Item 2", "$200"],
+        ["Category A", "Item 3", "$300"],
+        ["Category A", "Item 4", "$400"],
+        ["Category A", "Item 5", "$500"],
+        // ... ALL 50 rows must be included ...
+        ["Category A", "Item 50", "$5000"]
+    ],
+    "metadata": {
+        "row_count": 50,
+        "column_count": 3,
+        "has_headers": true,

+        "nested_tables": false,
+        "table_type": "data"
+    }
+}
+```
+
+### Nested Tables
+For tables containing other tables:
+1. Extract the outer table structure
+2. Represent nested tables as a JSON string or structured representation
+3. Ensure the data remains usable
+

+
+## Critical Data Integrity Rules
+
+1. **COMPLETENESS**: Extract EVERY row, no matter how many (10, 100, 1000+)
+2. **ACCURACY**: Preserve exact values, including formatting
+3. **STRUCTURE**: Maintain consistent column count across all rows
+4. **VALIDATION**: Ensure output is valid JSON that can be parsed
+5. **ESCAPING**: Properly escape quotes and special characters in cell values
+
+## Special Handling Instructions
+
+### Large Tables
+- Never abbreviate or summarize
+- Never use "..." to indicate omitted rows
+- Process every row even if it takes significant time
+- The metadata row_count must match actual extracted rows
+
+### Complex Merged Cells
+- Track rowspan/colspan values carefully
+- Ensure proper cell duplication
+- Maintain data alignment across all rows
+
+### Data Types
+- Keep numbers as strings to preserve formatting
+- Preserve currency symbols, percentages, etc.
+- Handle empty cells as empty strings ""
+
+### Error Prevention
+- If a cell contains quotes, escape them properly
+- Handle newlines within cells appropriately
+- Ensure no JSON syntax errors
+
+## Output Validation
+
+Before returning results:
+1. Verify JSON is valid and parseable
+2. Confirm row count matches actual data
+3. Check that all rows have same column count
+4. Ensure all data is preserved without truncation
+

+# 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(
+    table_score_threshold=5,      # Lower = more permissive
+    min_rows=3,                   # Require at least 3 rows
+    min_cols=2,                   # Require at least 2 columns
+    verbose=True                  # Detailed logging
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy,
+    css_selector="article.content", # Target specific content
+    exclude_domains=["ads.com"],   # Exclude ad domains
+    cache_mode=CacheMode.BYPASS    # Fresh extraction
+)
+```
+
+## 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['caption'] = table_data.get('caption', '')
+            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)
+        
+        for i, table in enumerate(result.tables):
+            # 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:
+                continue
+            
+            # Must contain numbers if required
+            if self.require_numbers:
+                numbers = self.number_pattern.findall(table_text)
+                if len(numbers) < 3:  # Arbitrary minimum
+                    continue
+            
+            # Extract the table data
+            table_data = self._extract_financial_data(table)
+            if table_data:
+                tables_data.append(table_data)
+        
+        return tables_data
+    
+    def _extract_financial_data(self, table):
+        """Extract and clean financial data from table."""
+        headers = []
+        rows = []
+        
+        # Extract headers
+        for th in table.xpath(".//thead//th | .//tr[1]//th"):
+            headers.append(th.text_content().strip())
+        
+        # Extract and clean rows
+        for tr in table.xpath(".//tbody//tr | .//tr[position()>1]"):
+            row = []
+            for td in tr.xpath(".//td"):

+                row.append(text)
+            if row:
+                rows.append(row)
+        
+        return {
+            "headers": headers,
+            "rows": rows,
+            "caption": self._get_caption(table),
+            "summary": table.get("summary", ""),
+            "metadata": {
+                "type": "financial",
+                "row_count": len(rows),
+                "column_count": len(headers) or len(rows[0]) if rows else 0
+            }
+        }
+    
+    def _get_caption(self, table):
+        caption = table.xpath(".//caption/text()")
+        return caption[0].strip() if caption else ""
+
+# Usage
+strategy = FinancialTableExtractor(
+    currency_symbols=['$', 'EUR'],
+    require_numbers=True
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### Example: Specific Table Extractor
+
+```python
+class SpecificTableExtractor(TableExtractionStrategy):
+    """Extract only tables matching specific criteria."""
+    
+    def __init__(self, 
+                 required_headers=None, 
+                 id_pattern=None,
+                 class_pattern=None,
+                 **kwargs):
+        super().__init__(**kwargs)
+        self.required_headers = required_headers or []
+        self.id_pattern = id_pattern
+        self.class_pattern = class_pattern
+    
+    def extract_tables(self, element, **kwargs):
+        tables_data = []
+        
+        for table in element.xpath(".//table"):
+            # Check ID pattern
+            if self.id_pattern:
+                table_id = table.get('id', '')
+                if not re.match(self.id_pattern, table_id):
+                    continue
+            
+            # Check class pattern
+            if self.class_pattern:
+                table_class = table.get('class', '')
+                if not re.match(self.class_pattern, table_class):
+                    continue
+            
+            # Extract headers to check requirements
+            headers = self._extract_headers(table)
+            
+            # Check if required headers are present
+            if self.required_headers:
+                if not all(req in headers for req in self.required_headers):
+                    continue
+            
+            # Extract full table data
+            table_data = self._extract_table_data(table, headers)
+            tables_data.append(table_data)
+        
+        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
+)
+```

+# 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.
