Align controls - Microsoft Office Excel

Select the controls to align.
Select the dominant control.
From the Format menu, choose Align.
From the cascading menu, choose one of the following to align the specified part of each selected control with the same part of the dominant control:
- Lefts - to align the left edge.
- Centers - to align the center of each control. This means a vertical line drawn at the center of the dominant control would contain the center of every selected control.
- Rights - to align the right edge.
- Tops - to align the top.
- Middles - to align the center of each control. This means a horizontal line drawn at the center of the dominant control would also contain the center of every selected control.
- Bottoms - to align the bottom.
- To Grid - to align the upper left corner of each selected control with its nearest grid point. Note that this option is not based on the position of the dominant control.

Note
Each command on the menu has a small picture that shows how the controls will be aligned.
