[O] 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
