Some of the data displayed in your tables may not be useful to you, or it may complicate the table unnecessarily. Fortunately, you can hide entire rows or columns without losing any data.

Activate (double-click) the Education Level table.

Ctrl-Alt click on the Valid Percent column label to select all the cells in that column.

Right-click the highlighted column and select Hide Category from the pop-up context menu.

The column is now hidden, but not deleted. If you want to redisplay this column...

From the menus choose:

View
Show All

Rows can be hidden and displayed in the same way as columns.
