[PSF-Community] Python library to extract data tables from PDF files

[Vinayak Mehta]

Hello David!

Yes, I've created a wiki page comparing Camelot with other open source
tools and libraries. tabula-py is a wrapper over tabula-java, which is used
by Tabula. You can check out the comparison of Camelot with Tabula here
<https://github.com/socialcopsdev/camelot/wiki/Comparison-with-other-PDF-Table-Extraction-libraries-and-tools#tabula>.
As you can see in the comparison, it outperforms Tabula in almost all cases!

While Tabula either gives either good output or fails miserably, Camelot
gives you complete control over the extraction process with various
configuration parameters! You can check out this section of the README
<https://github.com/socialcopsdev/camelot#why-camelot> for more
information. Camelot also lets you plot various geometries like detected
lines, intersections, tables in the PDF to debug and improve table
extraction! You can check out this part of the documentation
<https://camelot-py.readthedocs.io/en/latest/user/advanced.html#plot-geometry>
for more information on that.

Try it out!
