It's not. It's just something not implemented. And, as I see it, it
would be complicated to implement.
What you want seems to be this:
1. It's recommended to put the column headers into the <thead> element
(Org-mode does this). That way column headers are re-printed on every
page, if a table exceeds the size of one printed page.
2. It's recommended to use <th> elements in tables like this:
| Country | Number of citizens |
|---------+--------------------|
| Germany | 84 Mio. |
| France | XXX Mio. |
In this case it could make sense to put the country names in <th>
tags (see 4.). I think this is, what you wanted.
3. Use the caption element to describe the purpose of a
table. Org-mode does this.
4. The `scope' attribut describes, wich table cells are concerned by
the <th> element.
Again, our country example. This table should be handled corretly
by a screen reader:
<table>
<caption>Citizens per country</caption>
<thead>
<tr>
<th scope="col"> Country </th>
<th scope="col"> Number of citizens </th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row"> Germany </th>
<td> 84 Mio. </td>
</tr>
<tr>
<th scope="row"> France </th>
<td> XXX Mio. </td>
</tr>
...
There are more possible values for `scope' (`colgroup' and `rowgroup')
as well, as some additional possibilities to assign headers to cells
(`header' and `id') in such a way, that multiple headers describe one
cell.
In our example, the headers `Germany' and `Number of citizens' would
describe the cell `84 Mio.'.
I don't see, how Org-mode could decide which headers describe wich
cells.
The most obvious thing to do would be, to
a) mark cells as table-headers (this is the only needed new
Org-syntax feature),
b) if in the first table row, add a scope="col" to the <th> tag,
c) if in the first column, add a scope="row" to the <th> tag.
Beacuse if we take all those possible assignments into account, we'll
get something complicated to code, use and document...
We would have to end with some kind of `formular' syntax, like the one
used for the spreadsheet capabilities.

Sebastian
