feat: Add table extraction strategies and API documentation

- Implemented table extraction strategies: default, LLM, financial, and none in utils.py.
- Created new API documentation for table extraction endpoints and strategies.
- Added integration tests for table extraction functionality covering various strategies and error handling.
- Developed quick test script for rapid validation of table extraction features.

+# Table Extraction API Documentation
+
+## Overview
+
+The Crawl4AI Docker Server provides powerful table extraction capabilities through both **integrated** and **dedicated** endpoints. Extract structured data from HTML tables using multiple strategies: default (fast regex-based), LLM-powered (semantic understanding), or financial (specialized for financial data).

+8. [Error Handling](#error-handling)
+
+---
+
+## Quick Start
+
+### Extract Tables During Crawl
+
+```bash
+curl -X POST http://localhost:11235/crawl \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com/financial-data"],
+    "table_extraction": {
+      "strategy": "default"
+    }
+  }'
+```
+
+### Extract Tables from HTML
+
+```bash
+curl -X POST http://localhost:11235/tables/extract \
+  -H "Content-Type: application/json" \
+  -d '{
+    "html": "<table><tr><th>Name</th><th>Value</th></tr><tr><td>A</td><td>100</td></tr></table>",
+    "config": {
+      "strategy": "default"
+    }
+  }'
+```
+
+---
+
+## Extraction Strategies
+
+### 1. **Default Strategy** (Fast, Regex-Based)
+
+Best for general-purpose table extraction with high performance.
+
+```json
+{
+  "strategy": "default"
+}
+```
+
+**Use Cases:**
+- General web scraping
+- Simple data tables
+- High-volume extraction
+
+### 2. **LLM Strategy** (AI-Powered)
+
+Uses Large Language Models for semantic understanding and complex table structures.
+
+```json
+{
+  "strategy": "llm",
+  "llm_provider": "openai",
+  "llm_model": "gpt-4",
+  "llm_api_key": "your-api-key",
+  "llm_prompt": "Extract and structure the financial data"
+}
+```
+
+**Use Cases:**
+- Complex nested tables
+- Tables with irregular structure
+- Semantic data extraction
+
+**Supported Providers:**
+- `openai` (GPT-3.5, GPT-4)
+- `anthropic` (Claude)
+- `huggingface` (Open models)
+
+### 3. **Financial Strategy** (Specialized)
+
+Optimized for financial tables with proper numerical formatting.
+
+```json
+{
+  "strategy": "financial",
+  "preserve_formatting": true,
+  "extract_metadata": true
+}
+```
+
+**Use Cases:**
+- Stock data
+- Financial statements
+- Accounting tables
+- Price lists
+
+### 4. **None Strategy** (No Extraction)
+
+Disables table extraction.
+
+```json
+{
+  "strategy": "none"
+}
+```
+
+---
+
+## Integrated Extraction
+
+Add table extraction to any crawl request by including the `table_extraction` configuration.
+
+### Example: Basic Integration
+
+```python
+import requests
+
+response = requests.post("http://localhost:11235/crawl", json={
+    "urls": ["https://finance.yahoo.com/quote/AAPL"],
+    "browser_config": {
+        "headless": True
+    },
+    "crawler_config": {
+        "wait_until": "networkidle"
+    },
+    "table_extraction": {
+        "strategy": "financial",
+        "preserve_formatting": True
+    }
+})
+
+data = response.json()
+for result in data["results"]:
+    if result["success"]:
+        print(f"Found {len(result.get('tables', []))} tables")
+        for table in result.get("tables", []):
+            print(f"Table: {table['headers']}")
+```
+
+### Example: Multiple URLs with Table Extraction
+
+```javascript
+// Node.js example
+const axios = require('axios');
+
+const response = await axios.post('http://localhost:11235/crawl', {
+  urls: [
+    'https://example.com/page1',
+    'https://example.com/page2',
+    'https://example.com/page3'
+  ],
+  table_extraction: {
+    strategy: 'default'
+  }
+});
+
+response.data.results.forEach((result, index) => {
+  console.log(`Page ${index + 1}:`);
+  console.log(`  Tables found: ${result.tables?.length || 0}`);
+});
+```
+
+### Example: LLM-Based Extraction with Custom Prompt
+
+```bash
+curl -X POST http://localhost:11235/crawl \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com/complex-data"],
+    "table_extraction": {
+      "strategy": "llm",
+      "llm_provider": "openai",
+      "llm_model": "gpt-4",
+      "llm_api_key": "sk-...",
+      "llm_prompt": "Extract product pricing information, including discounts and availability"
+    }
+  }'
+```
+
+---
+
+## Dedicated Endpoints
+
+### `/tables/extract` - Single Extraction
+
+Extract tables from HTML content or by fetching a URL.
+
+#### Extract from HTML
+
+```python
+import requests
+
+html_content = """
+<table>
+  <thead>
+    <tr><th>Product</th><th>Price</th><th>Stock</th></tr>
+  </thead>
+  <tbody>
+    <tr><td>Widget A</td><td>$19.99</td><td>In Stock</td></tr>
+    <tr><td>Widget B</td><td>$29.99</td><td>Out of Stock</td></tr>
+  </tbody>
+</table>
+"""
+
+response = requests.post("http://localhost:11235/tables/extract", json={
+    "html": html_content,
+    "config": {
+        "strategy": "default"
+    }
+})
+
+data = response.json()
+print(f"Success: {data['success']}")

+```
+
+#### Extract from URL

+    }
+})
+
+data = response.json()
+for table in data['tables']:
+    print(f"Table with {len(table['rows'])} rows")
+```
+
+---
+
+## Batch Processing

+print(f"Total tables: {data['summary']['total_tables_extracted']}")
+
+for result in data['results']:
+    if result['success']:
+        print(f"  {result['source']}: {result['table_count']} tables")

+
+### Integrated Crawl Response
+
+Tables are included in the standard crawl result:
+
+```json
+{
+  "success": true,
+  "results": [
+    {
+      "url": "https://example.com",
+      "success": true,
+      "html": "...",
+      "markdown": "...",
+      "tables": [
+        {
+          "headers": [...],
+          "rows": [...]
+        }
+      ]
+    }
+  ]
+}
+```
+
+---
+
+## Error Handling
+
+### Common Errors
+
+#### 400 Bad Request
+
+```json
+{
+  "detail": "Must provide either 'html' or 'url' for table extraction."
+}
+```
+
+**Cause:** Invalid request parameters
+
+**Solution:** Ensure you provide exactly one of `html` or `url`
+
+#### 400 Bad Request (LLM)
+
+```json
+{
+  "detail": "Invalid table extraction config: LLM strategy requires llm_provider, llm_model, and llm_api_key"
+}
+```
+
+**Cause:** Missing required LLM configuration
+
+**Solution:** Provide all required LLM fields
+
+#### 500 Internal Server Error
+
+```json
+{
+  "detail": "Failed to fetch and extract from URL: Connection timeout"
+}
+```
+
+**Cause:** URL fetch failure or extraction error
+
+**Solution:** Check URL accessibility and HTML validity
+
+### Handling Partial Failures in Batch
+
+```python
+response = requests.post("http://localhost:11235/tables/extract/batch", json={
+    "url_list": urls,
+    "config": {"strategy": "default"}
+})
+
+data = response.json()
+
+successful_results = [r for r in data['results'] if r['success']]
+failed_results = [r for r in data['results'] if not r['success']]
+
+print(f"Successful: {len(successful_results)}")
+for result in failed_results:
+    print(f"Failed: {result['source']} - {result['error']}")
+```
+
+---
+
+## Best Practices
+
+### 1. **Choose the Right Strategy**
+
+- **Default**: Fast, reliable for most tables
+- **LLM**: Complex structures, semantic extraction
+- **Financial**: Numerical data with formatting
+
+### 2. **Batch Processing**
+
+- Use batch endpoints for multiple pages
+- Keep batch size under 50 items
+- Handle partial failures gracefully
+
+### 3. **Performance Optimization**
+
+- Use `default` strategy for high-volume extraction
+- Enable `preserve_formatting` only when needed
+- Limit `extract_metadata` to reduce payload size
+
+### 4. **LLM Strategy Tips**
+
+- Use specific prompts for better results
+- GPT-4 for complex tables, GPT-3.5 for simple ones
+- Cache results to reduce API costs
+
+### 5. **Error Handling**
+
+- Always check `success` field
+- Log errors for debugging
+- Implement retry logic for transient failures
+

+
+## Examples by Use Case
+
+### Financial Data Extraction
+
+```python
+response = requests.post("http://localhost:11235/crawl", json={
+    "urls": ["https://finance.site.com/stocks"],
+    "table_extraction": {
+        "strategy": "financial",

+        "extract_metadata": True
+    }
+})
+
+for result in response.json()["results"]:
+    for table in result.get("tables", []):
+        # Financial tables with preserved formatting
+        print(table["rows"])
+```
+
+### Product Catalog Scraping
+
+```python
+response = requests.post("http://localhost:11235/tables/extract/batch", json={
+    "url_list": [
+        "https://shop.com/category/electronics",
+        "https://shop.com/category/clothing",
+        "https://shop.com/category/books",
+    ],
+    "config": {"strategy": "default"}
+})
+
+all_products = []
+for result in response.json()["results"]:
+    if result["success"]:
+        for table in result["tables"]:
+            all_products.extend(table["rows"])
+
+print(f"Total products: {len(all_products)}")
+```
+
+### Complex Table with LLM
+
+```python
+response = requests.post("http://localhost:11235/tables/extract", json={
+    "url": "https://complex-data.com/report",
+    "config": {
+        "strategy": "llm",
+        "llm_provider": "openai",
+        "llm_model": "gpt-4",
+        "llm_api_key": "sk-...",
+        "llm_prompt": "Extract quarterly revenue breakdown by region and product category"
+    }
+})
+
+structured_data = response.json()["tables"]
