[Orgmode] Selective export of table columns

[Suvayu Ali]

Hi,

I recently was in a situation where I had tables like these,


|    | smear param | \chi^2/DoF  | \chi^2/DoF |
| Sl |  caloE perp | perp before | perp after |
|----+-------------+-------------+------------|
|  3 |       3.008 | 8/13        | 8.3/13     |
|  2 |       3.508 | 8/13        | 8.2/13     |
|  0 |       4.008 | 8/13        | 8.3/13     |
|  4 |       4.508 | 8.1/13      | 8.4/13     |


Now the 1st and 2nd column are something for my reference and I don't
want to export them to my presentation slides. So is there an option for
selective export of table columns? If not can someone give any hints how
I might try to achieve that? I am just learning some lisp, so maybe this
could be a good practice. :)

Thanks for any insights.
