Not really in practice to me. Especially they still struggle with Table format detection.

This.

Any complex parent table span cell relationship still has low accuracy.

Try the reverse, take a complex picture table and ask Chatgpt5, claude Opus 3.1, Gemini Pro 2.5 to produce a HTML table.

They will fail.

Maybe I misunderstood the assignment but it seems to work for me.

Edit: Just caught a mistake, transcribed one of the prices incorrectly.

Maybe my imagination is limited or our documents aren't complex enough, but are we talking about realistic written documents? I'm sure you can take a screenshot of a very complex spreadsheet and it fails, but in that case you already have the data in structured form anyway, no?

I had mentioned this when the new QWEN model dropped - I have a stack of construction invoices that fail through both OCR and OpenAI.

It's a hard (and very interesting) problem space.
