The "Default" settings used in all of the format menus (table element, table, table print, and application) can be set for the entire application. These "Default" settings are then accepted or changed for individual tables. Changing the default setting is the easiest way to change the formatting of all of your tables at once.

The "Default" Options menu is available under the Edit drop down menu and listed as "Preferences".
