Build a Tabula clone to handle data tables

Much to my dismay, defense appropriations bills (and perhaps other bills) include data tables which are laid out in text.

These tables (as @jazzido warned me about years ago) include text elements that span columns and all sorts of messes.  

Short of building a Tabula clone, it may be sufficient to notify users that tables show up on certain pages (and that they aren't being handled)
