[O] [BUG]? Constant-definition-lines in tables get exported.

[Yu]

Hello!

org-mode tables currently allow defining table-local constants in lines marked with "$" (as described in the "Tables > Advanced Features" section of the manual). 

However, when exporting (to LaTeX), these lines are included in the output -- and a cannot find a possibility to re-exclude them.

Using #+CONSTANTS: is no adequate replacement, as the table-local constants help to avoid accidentially defining a constant twice, maybe with different values. Also the local character allows to use shorter names, which are better understandable in the context, but maybe not at all outside.


An example table from my work:

|   | site               |  N |    E/N[eV] | E_surf[meV/A²] |
|---+--------------------+----+------------+----------------|

| * | on-top-1           | 32 | -7.2062959 |         138.89 |
| * | bridge-2           | 32 | -7.2063544 |         138.85 |

| * | bridge-3           | 32 | -7.2064131 |         138.81 |
| $ | e_bulk=-8.30623    |    |            |                |

| $ | e_bulk_zn=-1.26671 |    |            |                |
| $ | A_int=25.34335655  |    |            |                |

#+TBLFM: $5=1000*($4*$3-($3-4)*$e_bulk-4*$e_bulk_zn)/(2*$A_int);%.2f

My org-mode is a yesterday's pull from the git-repository.

kind regards, Yu
