Current Status: Currently, no tables of any sort are included when you print a wikipedia article as pdf. @cscott has started writing a patch to change that: https://gerrit.wikimedia.org/r/#/c/107587/. However, the patch does not cover all cases, and the layout is still an issue to solve.
Task: As a first step, create a version that adds all tables of an article to an appendix of the pdf.
- coming up with a good way to reference the tables in the article
- adding the tables to an appendix (it is probably out of the scope of a hackathon project to also make sure that the table always fits the page)
Please be aware that there are separate tasks for improving cscott's patch(T137431).
