reverse column or row.

reverse column or row.

[Uwe Brauer]

Hello

I think that one could "solve" the hebrew problem I mentioned yesterday,
if there were a function like org-table-reverse-column
(or org-table-reverse-row)
acting like reverse-region but just for columns or rows.

Unfortunately there is no function as reverse-rectangle or something
like this to start with.

Anybody has an idea?

Thanks

This again I see in the category of "fun with combinations of
reverse-region (to reverse lines) and org-table-transpose-table":

Reverse row(s): Isolate the row(s) by adding an empty line before and
after, transpose, reverse, transpose, remove added empty lines.

Reverse column(s): Transpose the whole table before and after the
steps above.

Maybe.

Aha by empty lines you really mean empty lines, not empty table lines?

That indeed works!
I transposed the table, kill the rectangular with the column I wanted to
reverse, yanked it and then applied reverse-region. Your idea is much
better.

To wrap it into a function seems not that trivial. However a
keyboard macro works just fine and is the poor's man solution to it.

Thanks.

Here is a function but it just works for one row, if anybody wants to
generalise it for more rows.......


(defun my-org-table-reverse-cells-in-row ()
  "Simple function to reverse cells in one row."
  (interactive)
  (save-excursion
	(end-of-line 1)
	(newline 1)
	(goto-char (org-table-begin))
