That is not entirely correct. Someone (I forgot who it was, sorry)
provided me with the following hack


(add-hook 'org-export-before-processing-hook
           'f-ox-filter-table-column-del)


(defun f-ox-filter-table-column-del (back-end)
   "Delete the columns $2 to $> marked as \"/\" on a row with \"/\" in $1.
 If you want a non-empty column $1 to be deleted make it $2 by
 inserting an empty column before or rearrange column order in
 some other way. Make sure \"/\" is in $1 again after that."
   (while (re-search-forward
           "^[ \t]*| +/ +|\\(.*?|\\)?? +\\(/\\) +|" nil t)
     (goto-char (match-beginning 2))
     (org-table-delete-column)
     (beginning-of-line)))


That is very useful and I wonder why there is nothing in org vanilla
(but then it might and I did not find it.)
