I propose to automatically add the scope-attribute to <th>-elements. This is usefull for non-graphical user clients, and also helps to a more semantic html. There was a request on de.wikipedia to add the attribute to infoboxes, which are often build like this:
<th> Description </th>
<td> Value </td>
I guess an algorithm like this:
The scope-attribute is appended to <th> when
* there is no wikitext-defined attribute (allows overwriting)
* the <th> is the first element in its row and when its the single <th>
* when it has a rowspan-attribute it gets "rowgroup"
* else it gets "row"
* there are only <th>s in this row
* when it has a colspan-attribute it gets "colgroup"
* else it gets "col"
* when its the first in its row we might check the row below? When there's also a <th> in the beginning we should set no scope-attribute. The best would be checking at which "coordinates" the first <td> appears, so everything left /or/ above could get a appropriate row/col-scope, everything left /and/ above should get nothing. This would work with headers grouped by cells a second row/column, too, but it's not easy to implement.
And we might have to watch for rtl-tables :-)
The scope attribute has a default value of “auto,” which responds to the table processing model in a predictable way. This proposal would replace that with a new, unpredictable default behaviour, and require us to add scope="auto" to restore normal behaviour.
The normal behaviour of th scope is complex enough, without having to learn another way it works in wiki tables, based on a far less detailed spec than the relevant part of HTML5.
I would prefer the scope attribute in wikis to work the same way it does in all other web pages.
