This is nice. I do quite a bit of tabular data extraction and pdf tables are often a sticking point. It is absolutely correct in describing it as a "fuzzy" problem.

My go-to solution has been 'pdftotext -layout' with a bit of hackery before giving it to pandas.read_fwf. That usually gets me 80% of the way there 80% of the time. The upside is that this tends to fail "better" than some other options.

I look forward to kicking-the-tires with this on my test cases.
