If you have never worked with templates, please make note!  This table template has very strict parameters.  If you (even accidentally) happen to "move" one of the table borders by dragging it with your mouse, the template will no longer perform properly. 

You may be able to drag it back so that it "appears" it is working properly, but FrontPage will have readjusted the variable portion of the template to a fixed number, and the fixed number will depend on what your OWN resolution is at the time you've done this.

If you EVER drag a table border in a pre-designed template, immediately go to Edit, Undo.  This is the only sure way to get the appropriate sizing back.
