If you want to stress-test a document AI system, give it a complex table.
Tables break systems because even subtle errors can destroy usability:
- Misaligned rows
- Broken headers
- Merged cells parsed incorrectly
- Lost relationships between labels and values
What matters isn’t just detecting a table. It’s reconstructing structure with enough fidelity that the output still works for analytics and downstream automation.
If the table isn’t usable, the document isn’t either.
