Due to the way PDF works, Infix can't tell what's a table and what's normal text without help.

You help it by drawing a special box around areas that it should treat at tabular.

To export a table:
  1. Draw a box around the table (called "marking-up" the table)
  2. Export the table on its own
  3. Export the table as part of a page
