Well the following works! #+begin_src elisp |----+----+----+---+---+----| | 1 | 4 | 5 | 3 | 3 | 6 | | 3 | 12 | 15 | 9 | 2 | 11 | | 12 | 2 | 14 | 7 | 3 | 10 | #+TBLFM: $3=vsum($1..$2);f1:: #one comment #+TBLFM: $6=vsum($4..$5);f1:: #second comment #+end_src > Once you had it then adding a comment character to it should be very simple. I hoped to add comments to the formula editor, but that most likely requires text-properties or overlays or something of that sort. Regards
