The FormView control, like the DataList control requires customization via templates. You'll have to go into templated editing mode and modify them that way. If you're looking for something quick, then maybe the GridView or DetailsView controls are the way to go?
Now, if you don't mind a control that you have to go in and modify using templates, I would recommend the Repeater. The Repeater control is the most flexible because basically you're responsible for building the structure by hand. So you could switch to code view, build an HTML-based table, then add the Repeater control to one of the <tr> tags in the HTML table. Let me know if any of this makes sense or if you need more direction.
Thanks for the awesome comments and thanks for picking up the book.
