Shading includes fill colors and patterns that you can apply to table cells.
Select the cell or cells you want to add shading to.
Click the Shading list arrow in the Table Tools Design tab.
The shading menu will show a spectrum of colors from the current document theme as well as a few standard colors. You could also select More Colors to select a custom color or select No Color to remove existing shading.
Select a color.
The color is added as a background to the selected cells.
To use a pattern instead of a solid color in your table, click the Borders group dialog box launcher, click the Shading tab, and select a pattern in the Style list.
