[O] Let org table support move region selected fields

Hi, recently I realized that table rows/columns movement does not
support region selection. Like following example.

| a | b | c |
| 1 | 2 | 3 |
| 4 | 5 | 6 |

When I use region select "5 | 6", and press "org-metaup [M-Up/Down]". It
does not work as expected move "5 | 6" up. Seems this command does not
region selection. Include "[M-Right/Left]" Is is possible to support
region selection so that partial movement will be great!
