I have a PDF with tables that appear without top and bottom border lines, causing them to not be detected by the prebuilt layout model. As a result, they are being detected as normal paragraphs. I need to detect a total of 2 tables, one from each PDF page. Issue: Table like these is not being detected (rather detected as normal paragraph, without table structure) Ideally Expected: Detect a total of 2 tables, one from each pdf page. I think this has to do with fine-tuning existing prebuilt layout model, but I don't see any option to perform this. What is the ideal way to overcome this issue?

How to make the prebuilt layout model detect tables with missing top and bottom border lines in a PDF??

Thanks for reaching out to us, you can try custom model as below document (you can not fine-tune the existing model directly but create a custom model) -

I hope this helps.
