feature proposal. Kill and yank columns

feature proposal. Kill and yank columns

[Uwe Brauer]

Hi

I know that I can delete columns but I miss a function which would
*kill* a column,  put it in the some ring (or register) and paste it.

I do this my marking the content of a column and use kill-rectangle and
yank-rectangle but I find such a solution which needs the mark,
cumbersome.

I goggled around and found for example proposals as in

https://stackoverflow.com/questions/22002374/how-to-select-a-column-of-a-table-in-emacs-org-mode

Which is basically the same I do. 

Or in

http://orgmode.org/worg/org-hacks.html#field-coordinates-in-formulas

Which seems complicated.

It also seems a subject which comes up regularly. Is this so difficult
to implement?

Thanks and regards

Some time ago I wrote this function:

(defun mw-org-table-mark-column ()
  "Mark the column containing point.
This works only in org tables.

For tables with horizontal lines this function can fail."
  (interactive)
  (unless (org-at-table-p) (user-error "Not at a table"))
  (org-table-find-dataline)
  (org-table-check-inside-data-field)
  (let* ((col (org-table-current-column))
         (beg (org-table-begin))
	 (end (org-table-end)))
    (goto-char beg)
    (org-table-goto-column col)
    (re-search-backward "|" nil t)
    (push-mark)
    (goto-char (1- end))
    (org-table-goto-column (1+ col))
    (re-search-backward "|" nil t)
    (exchange-point-and-mark)))

If you do M-x mw-org-table-mark-column followed by C-x SPACE in a
table-cell you (hopefully) the column gets marked.

This might be a start.

That is cool, thanks, unfortunately some of my tables contain horizontal
lines, but this is not really very essential for me.

Does `org-table-move-column' help, or do you mean to move the column to
a different table?

There are `org-table-cut-region', `org-table-copy-region' and
`org-table-paste-rectangle'. In any case, you'll need the mark.

If I need to mark the region in question, I could stick with
kill-rectangle and friends. The point is not to mark the column.

org-table-delete-column does not need the mark, so my hope is that this
code could be somehow  generalized. I played a bit around with that
function but so far no success.
