Why does datagrid output td and not th for headers

[taftor]

Why does datagrid output td and not th tags for the table headers, previously i simply applied my heading sytles to the th tag, and then i never needed to think about formating my table headers. Unfortunatly asp.net seems to ignore that tag and outputs its table header cells as td, so now i have to try formating each cell.<BR><BR>Anyone know a way of recreating the datagrid element so itll output th tags fo headers, or does anyone have any good suggestions on ways of not having to format tabel headers all the time.<BR><BR>Thanks<BR><BR>Kristian
