Nicolas,

Special blocks seem to work very well, actually. Thank you.

This is what you had proposed:

#+begin_threeparttable
  ...
  tabular with Org syntax
  ...
  #+begin_tablenotes
  ... probably some raw LaTeX...
  #+end_tablenotes
  #+end_threeparttable

It seem to work beautifully even when the table is a result of a source
code block. My experiments suggest that when the result changes, on account
of evaluating the source code block again, the special block structure
around is respected.

Super. I am amazed.

Thank you.

I bow.

Vikas
