* feature request: exporting TBLFM line, formatted or not

Hello,

For pedagogical reasons, it would be nice to be able, in some case, to
export a table (to LaTeX typically) with annotations (i.e. column and
row labels) and, more importantly, the equations used to populate the
table.  Is this possible somehow?

Obviously, for the row/column labelling, I could simply add an extra
column and row with those labels...

For the TBLFM aspect, thinking aloud but with no real knowledge, would
it be possible to create a filter, say, that maybe copies and transforms
a TBLFM line before being thrown away by the export engine?

Any suggestions welcome.

thanks,
eric

Bastien's table formulas tutorial does it this way:

--8<---------------cut here---------------start------------->8---
* Column formulas and field formulas

Ok, so now we have this table:

: | Student  | Maths | Physics | Mean |
: |----------+-------+---------+------|
: | Bertrand |    13 |      09 |   11 |
: | Henri    |    15 |      14 |      |
: | Arnold   |    17 |      13 |      |
: #+TBLFM: @2$4=vmean($2..$3)
--8<---------------cut here---------------end--------------->8---

Will that work for you?

It would but what I would really like is to have an option I can turn on
to enable me to process the TBLFM line for output but have the table
appear as normal.  I don't want to have the table in verbatim.

What I was thinking of is to have essentially a caption below the table
that presents the equations used.

Okay, a start on this using hooks:

#+begin_src emacs-lisp
  (defun esf/process-table-tblfm (backend)
    "Process the TBLFM line to make it available for export as a verbatim block"
    (while (re-search-forward "^ *#\\+TBLFM:" (point-max) t)
      (replace-match ":")
      (let ((start (point))
            (end (progn (forward-line) (point))))
        (goto-char start)
        (while (re-search-forward "::" end t)
          (replace-match "\n: ")))
      )
    )
  (add-hook 'org-export-before-parsing-hook 'esf/process-table-tblfm)
#+end_src 

I'm sure there's a much easier way to do this but, for now, this does
what I need.

thanks,
eric

You can write a custom back-end. All the TBLFM information is stored in
the table element.

Thanks for the suggestion.  I will explore this option.
