Delete Columns


The Delete Columns Table menu option allows the user to delete columns from a Table object. The user can select one or more columns for deletion. Note: This permanently deletes Columns from the table, and is different than a Filter, which just hides Columns. It can be accessed by going to Table | Columns| Delete Columns.
