Design ribbonAs part of the Office 2007 interface, additional tabs and menu items are revealed to the user when they are needed. In this case, a new high-level tab, Table Tools, is added to the interface whenever you are interacting with a table element inside of a Word document. The two tabs under Table Tools contain all of the various formatting tools you need to customize your table.
Once you create a table and populate it with data, the next step is to format the table. Proper formatting will help your table convey just the information you want it. In Word 2007, whenever you are inside a table within your document, the ribbon interface changes to the Design ribbon under Table Tools.
