remark-grid-tables: column headers

[artragis]

This is only a suggestion, if this seems too hard to perform it or too complex to include it to the plugin I understand this will be rejected.

I was writting a "truth table" for a tutorial and I was wondering if I could not make the columns be headers :

+---------+----------+----------+
|         |  C1 VRAI | C1 FAUX  |
+=========+==========+==========+
| C2 VRAI |  VRAI    |    FAUX  |
+=========+----------+----------+
| C2 FAUX |  FAUX    |    FAUX  |
+=========+----------+----------+

this would be interpreted as a table with the first row as header & the first column (we would have th instead of td in html)

<table>
    <thead>
        <tr>
            <th colspan="1" rowspan="1"></th>
            <th colspan="1" rowspan="1"><p>C1 VRAI</p></th>
            <th colspan="1" rowspan="1"><p>C1 FAUX</p></th>
        </tr>
     </thead>
     <tbody>
         <tr>
            <th colspan="1" rowspan="1"><p>C2 VRAI</p></th>
            <td colspan="1" rowspan="1"><p>VRAI</p></td>
           <td colspan="1" rowspan="1"><p>FAUX</p></td>
         </tr>
        <tr>
             <th colspan="1" rowspan="1"><p>C2 FAUX</p></th>
             <td colspan="1" rowspan="1"><p>FAUX</p></td>
             <td colspan="1" rowspan="1"><p>FAUX</p></td></tr></tbody></table>

Why not, although it may be quite hard to implement. remark-grid-tables is surprisingly complex.
