Subject: Help with fixing an org-mode multicolumn implementation - LaTeX special characters
Date: Sun, 21 Feb 2016 11:28:45 +0100 [thread overview]
Message-ID: <56C9915D.7080408@gmail.com> (raw)
I found a very nice implementation of LaTeX multicolumn functionality in
this thread:
https://lists.gnu.org/archive/html/emacs-orgmode/2013-02/msg00736.html
("using export filters to emulate multi-column table cells?")
#+begin_src emacs-lisp :exports none
(defun my-latex-multicolumn-filter (row backend info)
(when (org-export-derived-backend-p backend 'latex)
(while (string-match
"\\(<\\([0-9]+\\)col\\([lrc]\\)?>[[:blank:]]*\\([^&]+\\)\\)" row)
(let ((columns (string-to-number (match-string 2 row)))
(start (match-end 0))
(contents (replace-regexp-in-string "[[:blank:]]*$" ""
(match-string 4 row)))
(algn (or (match-string 3 row) "l")))
(setq row (replace-match
(format "\\\\multicolumn{%d}{%s}{%s}" columns algn
contents)
nil nil row 1))
(while (and (> columns 1) (string-match "&" row start))
(setq row (replace-match "" nil nil row))
(decf columns))))
row))
(add-to-list 'org-export-filter-table-row-functions
'my-latex-multicolumn-filter)
#+end_src
#+LATEX_HEADER: \usepackage{multirow}
You have to put the number of columns to span and a r / l / c option for
column alignment (<2colc>) and the column contents afterwards. Nice!
#+CAPTION: Example table
| Characters not working | <2colc> Characters working: ! " § . ,
* + ? % | |
|-------------------------------+-----------------------------------------------+------------------|
| ^ % _ { } $ | The header above is
merged | over two columns |
| /italics/ *bold* _underline_
| | |
| any, \LaTeX special character
| | |
| or expression requiring \
| | |
However, using any of the characters of the left column of my example
table in the merged <2colc> column, I get:
"setq: Invalid use of `\' in replacement text"
Questions:
- How to escape the special characters in the left column properly to be
able to use them? (tried everything I could think of)
or
- How to modify the code above so that it allows for such characters.
- If anyone likes the implementation and is more capable than I am, then
the same for multirow would be really nice...
Comment: whoever read some of my questions recently will notice that I
excessively use org-mode as a LaTeX frontend. I am aware that this is
not what it is supposed to be in the first place - but it works so
perfect 99 % of the time, so I cannot keep from asking...
