[O] Transpose or open functions for table cells

[Suvayu Ali]

Hi,

I was wondering if there are any transpose functions for table cells;
something akin to transpose-lines, or transpose-words.  I am also
looking for something like org-open-line, but only for a table cell.
This is my use case:

| col 1 | col 2 |       | col 1 | col 2 |
|-------+-------+       +-------+-------|
|     1 | a     |       |     1 | a     |
|     2 | b     |  -->  |     2 | b     |
|     3 | d     |       |     3 |       |
|     4 | e     |       |     4 | d     |
|     5 |       |       |     5 | e     |

If neither exists, any thoughts how might one go about writing one?

Thanks for any ideas.
