Re: Fwd: comment lines inside org tables

[Rolf Sander <rolf.sander@mpic.de>]

Hello Nicolas,

I want to add a comment line into the file that does not disturb the
table. Like a "|---+---+---|" hline. I don't want any action. All
programming languages have the option to add comments to the source
code. The comment does not trigger any action, and the result of
executing the code is the same, whether with or without comment lines.
It would be nice if org-tbl would allow comment lines as well.

> Anyway, in the general case, there is no way to comment a row.

Okay, so my question turns into a feature request now...

I have started to modify defun org-table-align. With the modification,
org-tbl now ignores all lines starting with "|-/". For me it works fine.
However, please let me know if you see any side-effects. You can
download the full defun here:

And here is a diff to the original code:
