Thanks for sharing.  How does it deal with footnotes in tables?
(That is one thing that longtable does better.)

  Hello guys.
  I don't like how longtable handle with tables, spanning across pages
  without needing, so I took advantage of the filtering mechanism and I
  did a filter in python to generate the tables in a more traditional way
  (in the sense of Latex) and I'm sharing with you below.
  Please make suggestions, I did the things a few hardcoded because I
  didn't see other way.
  To understand what the filter do, let's say I have a file with the
  following table:
  test.mkd
