can I put EditCommandColumn within table tags?

I am displaying a datagrid, but in a form style so that the user can edit the one record that they are looking at. I am using table tags within a template column to achieve this. I then want to add an EditCommandColumn to allow editing. Can I have this column displaying in the centre of the screen, below my template column. At the moment I can only get it to display to the right as it won't allow for table tags?
