How to Automatically Add Table Borders in a Misaligned PDF?

[88arvin]

I have a PDF that contains tables but the columns are not properly aligned across pages. I know that I can explicitly draw vertical lines to create borders, but the misalignment varies from page to page, I would have to do this manually for each page, which is time-consuming.

Is there a way to automatically add vertical borders to the tables without explicitly drawing lines on every page?

Any suggestions would be appreciated!

I believe pdfplumber cannot meet your requirement—it can only read and parse PDFs, not edit or modify them. However, if you are sure the content are tables, you can extract each line’s bbox relative positions with pdfplumber and then use another third-party library to regenerate the table or directly output it as a Markdown table.
