KG-DWN-98-2 Audited EOY-2013-14.pdf Kindly look at page 7 table. It is not able to exract table info. I am using tesseract. Kindly advice.

This library simply uses the results of OCR (Optical Character Recognition) you specify, so I bet the issue lies in the OCR configuration. Have you tried other OCR tools, such as DocTR?

DocTR gives me better (not good tho) results than Tesseract
