## 1. Core Algorithm Implementation
|
|
|
|
### 1.1 Grid Inference Module
|
|
- [x] 1.1.1 Create `CellBoxGridInferrer` class in `pdf_table_renderer.py`
|
|
- [x] 1.1.2 Implement `cluster_values()` for Y/X coordinate clustering
|
|
- [x] 1.1.3 Implement `infer_grid_from_cellboxes()` main method
|
|
- [x] 1.1.4 Add row_heights and col_widths calculation
|
|
|
|
### 1.2 Content Mapping
|
|
- [x] 1.2.1 Implement `extract_cell_contents()` from HTML
|
|
- [x] 1.2.2 Implement `map_content_to_grid()` for row-by-row assignment
|
|
- [x] 1.2.3 Handle content count mismatch (more/fewer cells)
|
|
|
|
## 2. PDF Generator Integration
|
|
|
|
### 2.1 New Rendering Path
|
|
- [x] 2.1.1 Add `render_from_cellboxes_grid()` method to TableRenderer
|
|
- [x] 2.1.2 Integrate into `draw_table_region()` with cellboxes-first check
|
|
- [x] 2.1.3 Maintain fallback to existing HTML-based rendering
|
|
|
|
### 2.2 Cell Rendering
|
|
- [x] 2.2.1 Draw cell borders using cell_boxes coordinates
|
|
- [x] 2.2.2 Render text content with proper alignment and padding
|
|
- [x] 2.2.3 Handle multi-line text within cells
|
|
|
|
## 3. Configuration
|
|
|
|
### 3.1 Settings
|
|
- [x] 3.1.1 Add `table_rendering_prefer_cellboxes: bool = True`
|
|
- [x] 3.1.2 Add `table_cellboxes_row_threshold: float = 15.0`
|
|
- [x] 3.1.3 Add `table_cellboxes_col_threshold: float = 15.0`
|
|
|
|
## 4. Testing
|
|
|
|
### 4.1 Unit Tests
|
|
- [x] 4.1.1 Test grid inference with various cell_box configurations
|
|
- [x] 4.1.2 Test content mapping edge cases
|
|
- [x] 4.1.3 Test coordinate clustering accuracy
|
|
|
|
### 4.2 Integration Tests
|
|
- [ ] 4.2.1 Test with `scan.pdf` Table 7 (the problematic case)
|
|
- [ ] 4.2.2 Verify no regression on existing table tests
|
|
- [ ] 4.2.3 Visual comparison of output PDFs
|
|
|
|
## 5. Documentation
|
|
|
|
- [x] 5.1 Update inline code comments
|
|
- [x] 5.2 Update spec with new table rendering requirement
