# Implementation Tasks

## Phase 1: Core Fix - Table Content Conversion

### 1.1 Add TableData.from_dict() class method
- [ ] In `unified_document.py`, add `from_dict()` method to `TableData` class
- [ ] Handle conversion of cells list (list of dicts) to `TableCell` objects
- [ ] Preserve rows, cols, headers, caption fields

### 1.2 Fix _json_to_document_element for TABLE elements
- [ ] In `pdf_generator_service.py`, modify `_json_to_document_element`
- [ ] When `elem_type == ElementType.TABLE` and content is dict with 'cells', convert to `TableData`
- [ ] Use `TableData.from_dict()` for clean conversion

### 1.3 Verify TableData.to_html() generates correct HTML
- [ ] Test that `to_html()` produces parseable HTML with proper row/cell structure
- [ ] Verify colspan/rowspan attributes are correctly generated
- [ ] Ensure empty cells are properly handled

## Phase 2: OCR Track Rendering Consistency

### 2.1 Review convert_unified_document_to_ocr_data
- [ ] Verify TableData objects are properly converted to HTML
- [ ] Add fallback handling for dict content with 'cells' key
- [ ] Log warning if content cannot be converted to HTML

### 2.2 Review draw_table_region
- [ ] Verify HTMLTableParser correctly parses generated HTML
- [ ] Check that ReportLab Table is positioned at correct bbox
- [ ] Verify font and style application

## Phase 3: Testing and Verification

### 3.1 Test OCR Track
- [ ] Test scan.pdf - verify tables have correct structure
- [ ] Test img1.png, img2.png, img3.png
- [ ] Compare generated PDF with original documents

### 3.2 Test Direct Track (Regression)
- [ ] Test PDF files with Direct track
- [ ] Verify table rendering unchanged

### 3.3 Test Hybrid Mode
- [ ] Test files that trigger hybrid processing
- [ ] Verify mixed Direct + OCR elements render correctly

## Phase 4: Code Quality

### 4.1 Add logging
- [ ] Add debug logging for table content type detection
- [ ] Log conversion steps for troubleshooting

### 4.2 Error handling
- [ ] Handle malformed cell data gracefully
- [ ] Log warnings for unexpected content formats
