Bug
When attempting to open an Excel document with complex tables, Docling fails to extract the tables correctly.
Steps to reproduce
from docling.document_converter import DocumentConverter
source = "./excel-tests.xlsx" # document per local path or URL
converter = DocumentConverter()
result = converter.convert(source)
print(result.document.export_to_markdown()) # output: "## Docling Technical Report[...]"
excel-tests.xlsx

Final Considerations
I understand that the table is complex, so I would like to know what would be the requirements for an Excel document to work with Docling. Digging into the code, I noticed this:
Hope it helps,
Let me know if you need more information.
Have a nice day!
