Word 97 and 2000 add a thin, printing border around every table you insert. That's fine if you want a border but annoying if you don't. Worse, there's no way to change this default. There is, however, an undocumented way to eliminate the borders that doesn't require a trip to Word's Table-Autoformat: immediately after inserting a table with the Insert-Table command, press <Ctrl>-<Alt>-U and the border disappears.
