Org Babel "swallows" table column groups

Org Babel "swallows" table column groups

[Rudolf Adamkovič]

Given the source block

  #+BEGIN_SRC emacs-lisp
  (list (list 1 2) (list "/" "<>") 'hline (list 3 4) (list 5 6))
  #+END_SRC

Org Babel outputs

  #+RESULTS:
  | 1 | 2 |
  |---+---|
  | 3 | 4 |
  | 5 | 6 |

with the second element of the list

  (list "/" "<>")

swallowed, without a word.

Why would Org Babel do this?

And, how can one output tables with column groups?

This is because of how `orgtbl-to-generic' is implemented. It is taking
pieces from the full ox.el exporter, hard-coding certain things. For
example, it always removes special table lines:

    ;; Since we are going to export using a low-level mechanism,
    ;; ignore special column and special rows manually.

ox.el used to do the same recently, until I added a feature to keep
special lines in tables during export (for ox-org purposes).

Bummer!

I wrote a little Scheme program to generate truth tables for my notes on
mathematical logic and also to aid future explorations.  It works well,
but without table separators, truth tables are harder to read.

I refactored `orgtbl-to-generic', so that it does not have to duplicate
`org-export-as'. Now, things should be more consistent with the normal
export.

May you try the attached tentative patch set?

Given the source block

  #+BEGIN_SRC emacs-lisp
  (list (list 1 2) (list "/" "<>") 'hline (list 3 4) (list 5 6))
  #+END_SRC

Org Babel outputs

  #+RESULTS:
  | 1 | 2 |
  |---+---|
  | 3 | 4 |
  | 5 | 6 |

with the second element of the list

  (list "/" "<>")

swallowed, without a word.

Why would Org Babel do this?

And, how can one output tables with column groups?

From what I see, the culprit is the "/" because, as soon as it appears,
Org Babel drops the row from the output.  Then, when I replace the "/"
with something different, such as "xyz", the row is back.

I stumbled upon the problem when using Scheme.  The bug report uses
Emacs Lisp only to ease reproduction.  (I should have probably mentioned
that.)  In other words, the problem does not seem to be specific to
Emacs Lisp.

It's weird because with swapping "<>" and "/" with escape-syntax character has no problem in the table:

#+BEGIN_SRC emacs-lisp
   (list (list 1 2) (list "\<>" "\/") 'hline (list 3 4) (list 5 6))
#+end_src

#+RESULTS:
|  1 | 2 |
| <> | / |
|----+---|
|  3 | 4 |
|  5 | 6 |
