Subject Re: How to logically read text from a PDF table?
Date Tue, 18 Jul 2017 15:31:44 GMT
Hi Dane,

As you might know, there's no thing such as tables in PDF files. The only
way to extract them is to try to reconstruct the tabular arrangement from
the characters' positions, ruling lines, and so on. I'm one of the
maintainers of Tabula [1], which is a tool based on PDFBox that implements
a number of algorithms to attempt that. We have a GUI tool [2], and a Java
library [3]. Both are open source (MIT license)
