Changes the tables, or changes the layout?
Changing the text size will change the layout as bigger text endeavours
to fit into the same space, there is nothing you can do about this. You
should always test your pages in different browsers, with different
browser sizes, and change to the largest text size available (using
View->Text Size, since other methods may ZOOM the page in Opera and IE7
- not the same thing), then adjust your layout to accommodate the
changes.
