The easiest way to apply shading or highlighting to alternate rows is to make them a table. Tables also include tools to help you analyze your data. However, if you want only table style formatting, you can remove the additional table functionality.
On the sheet, select the range of cells that you want to shade.
The cells can be empty or can contain data; if they contain data, the first row becomes the header row.
On the Tables tab, under Table Styles, click the style that you want.
To remove the sort and filter arrows, on the Tables tab, under Tools, click Convert to Range, and then click Yes.
