Ask HN: What's the current best way to extract tables from PDFs?

I am have a set of pdf that are bank statements. The formats of these statements are different based on the bank but they are limited set (<15). What's the current best approach to extract tabular data from PDFs? I tried writing custom logic based on pdfplumber and such but they are very fragile and have lots of ad-hoc logic. The maintenance is pretty high. Are there small models that can run preferably on CPUs alone and that I can possibly fine tune for this task? Any guides or pointers for that? I see a lot of available models, but as someone with no ML background, it's difficult to navigate through.
