Have short comments at bottom of table in org mode (beamer/latex export)

Question

I'm trying to make a table like so:

|   |  x |   y |
| a | 12 | 354 |
| b | 45 |  65 |

Then when I export it to pdf via beamer/latex I'd like to have a short comment below it (like Souce: www.google.com). Is this possible to do?

Answer 1

After much google-ing, I've found a way to make this happen. It relies on the LaTeX package threeparttable so you must add that to your org preamble:

#+LATEX_HEADER: \usepackage{threeparttable}

You can then add comments in the following manner:

#+begin_table
#+begin_threeparttable
#+ATTR_LATEX: :environment tabular :width \textwidth :center nil
|   |  x |   y |
| a | 12 | 354 |
| b | 45 |  65 |
#+begin_tablenotes
  \item[] here are some notes \item[] Here's a note on a new line
#+end_tablenotes
#+end_threeparttable
#+end_table

Which produces a nicely-formatted table as a pdf through beamer.
