When running the hybrid parser on multiple pages, for example this document:
hybrid_multipage.pdf
camelot -p all -f csv -o foo.csv hybrid hybridtest.pdf
camelot will output an extra, empty file on the second page. In the case of a document (which I definitely cannot share) of 59 pages, the final page will have 58 empty tables. As you can imagine this gets really unwieldy with Excel output.
The fix is really, really simple, a PR will be provided momentarily :-)
