Missing table in docling document

[az-ihsan]

Hi,

I convert the document into docling document and when I do the filtering of the DocItemLabel.TABLE, some of the tables are missing. Below is a code snippet.

def extract_lookup_pages(doc: DoclingDocument) -> Dict[str, int]:
    """Extract lookup pages from a document."""
    header_tables = []
    for item, _ in doc.iterate_items(included_content_layers={ContentLayer.BODY}):
        if getattr(item, "label", None) == DocItemLabel.TABLE:
            # You may want to refine this filter for your specific header location
            header_tables.append(item)
            header_text = "\n".join(
                    [" | ".join(cell.text for cell in row) for row in item.data.grid]
                )
            print(header_text)
    return extract_table_of_contents(header_tables)

I realize that there are missing table if run the snippet above. BUT, when I convert it into Markdown or doctags, the tables are there. do you have any idea why it happens?

cheers,
