# document-processing Specification Delta

|
## MODIFIED Requirements
|
|
|
|
### Requirement: Extract table structure (Modified)
|
|
|
|
The system SHALL use cell_boxes coordinates as the primary source for table structure when rendering PDFs, with HTML parsing as fallback.
|
|
|
|
#### Scenario: Render table using cell_boxes grid
|
|
- **WHEN** rendering a table element to PDF
|
|
- **AND** the table has valid cell_boxes coordinates
|
|
- **AND** `table_rendering_prefer_cellboxes` is enabled
|
|
- **THEN** the system SHALL infer row/column grid from cell_boxes coordinates
|
|
- **AND** extract text content from HTML in reading order
|
|
- **AND** map content to grid cells by position
|
|
- **AND** render table borders using cell_boxes coordinates
|
|
- **AND** place text content within calculated cell boundaries
|
|
|
|
#### Scenario: Handle cell_boxes grid mismatch gracefully
|
|
- **WHEN** cell_boxes grid has different dimensions than HTML colspan/rowspan structure
|
|
- **THEN** the system SHALL use cell_boxes grid as authoritative structure
|
|
- **AND** map available HTML content to cells row-by-row
|
|
- **AND** leave unmapped cells empty
|
|
- **AND** log warning if content count differs significantly
|
|
|
|
#### Scenario: Fallback to HTML-based rendering
|
|
- **WHEN** cell_boxes is empty or None
|
|
- **OR** `table_rendering_prefer_cellboxes` is disabled
|
|
- **OR** cell_boxes grid inference fails
|
|
- **THEN** the system SHALL fall back to existing HTML-based table rendering
|
|
- **AND** use ReportLab Table with parsed HTML structure
|
|
|
|
#### Scenario: Maintain backward compatibility
|
|
- **WHEN** processing tables where cell_boxes grid matches HTML structure
|
|
- **THEN** the system SHALL produce identical output to previous behavior
|
|
- **AND** pass all existing table rendering tests
|
