When you add an item to a table you add a new row and specify the contents of each column in the row. When you edit an item you change the contents of columns within an existing row. The procedures for adding and editing are very similar since you're working with the same columns in either case.
To add a new table item, or edit an existing item:
To add a new item, right-click anywhere in the table and select New.
OR
To edit an existing item, right-click the row for that item and select Edit.
This displays the Add (or Edit) dialog box.
The dialog box provides fields for entering data into the configurable table columns. The fields vary for each data table. Refer to the applicable section for details on how to configure each table.
Click Save when you are finished.
