Function create_expanded_ocr_for_table 

pub fn create_expanded_ocr_for_table(
    text_regions: &[TextRegion],
    cells: &[TableCell],
    config: Option<&SplitConfig>,
) -> (Vec<TextRegion>, HashSet<usize>)

Creates expanded OCR results after splitting cross-cell boxes.

This is a convenience function that takes the original text regions, detects cross-cell boxes, splits them, and returns an expanded list of text regions suitable for table stitching.

Arguments

• text_regions - Original text regions from OCR.
• cells - Table cells.
• config - Optional split configuration.

Returns

A tuple of (expanded_regions, processed_indices) where:

• expanded_regions: New text regions after splitting
• processed_indices: Indices of original regions that were split
