To change the height of a header row, you can move the mouse pointer to the far top left corner, or right click on a header row and select "Change Header Row Height".

In order to change the row height, follow these steps:

1. Move the mouse pointer between header rows until the pointer looks like an equal sign (=).
2. Click and drag the mouse up or down to resize.

NOTE: To remove a row, drag the mouse pointer up until that row disappears.
