Let me start by confessing my limited knowledge of lisp.
I am trying to write a LaTeX export filter that should replace all table rows with cells having entries such as <3cid4> by \cmidrule{lr}{3-4}
The idea is to have a table row of this kind
| <2cid3> | <4cid5> | <6cid7> | | | | |
Which should be exported to
\cmidrule(lr){2-3} \cmidrule(lr){4-5} \cmidrule(lr){6-7}
This is as far as I have gone.
------
(defun org-export-cmidrule-filter-latex (row backend info)
(while (string-match
"\\(<\\([0-9]+\\)cid\\([0-9]+\\)?>[[:blank:]]*\\([^&]+\\)\\)" row)
(let ((start (string-to-number (match-string 2 row)))
(end (or (match-string 3 row) "l")))
(setq row (replace-match
(format "\\\\cmidrule(lr){%s-%s}" start end)
nil nil row 1))
(while (string-match "& \\| \\\\\\\\" row 0)
(setq row (replace-match "" nil nil row))
(decf start))
)
)
row)
------
The above filter works if I have only one or two <[0-9]cid[0-9]> strings in a row. It does not pick up the third <[0-9]cid[0-9]> string.
I would greatly appreciate if anyone could help improve this filter.

Could it be that you need to change the last + to *?
Haven't tried it, mind you.
