Hi Eric!

No, unfortunately not.  Arrays (tabular data) are written out using only
whitespace for formatting:

--8<---------------cut here---------------start------------->8---
*** simple example
    #+srcname: octave-simple
    #+begin_src octave :results output 
A = [1, 2; 3, 4];
disp(A)
    #+end_src

    #+results: octave-simple
    :    1   2
    :    3   4
--8<---------------cut here---------------end--------------->8---

Yes, that makes sense.

That's what I do at the moment, actually.

Mind you, org is able to take the output and convert it to a table
easily enough with =C-c |= (org-table-create-or-convert-from-region)
operating on the output if selected as a region.  Would it be possible
to post-process the output from babel automatically using this method
(maybe with a hook?)  with the output selected if ":results output
table", say, were specified?  That alone would be sufficient for 90% of
the cases...

Apologies for the sporadic nature of my responses lately: I have been on
holiday (much needed!) and purposely without email most of the time!

Thanks,
