Re: Scope-Attribute necessary for TH-Element?

Jonathan described it well.
If your <th> cells span a single column and are in the first row
scope="col" is not needed.
Ditto <th> cells in first column spanning a single row, scope="row" is
generally not needed.

If a <th> cell spans multiple rows/columns you need to use
scope="colgroup"/"rowgroup" along with the colspan/rowspan attribute.
If the <th> cell is not the first row or column in the table you need
the scope attribute.
