Apply preset object styles in Numbers for iCloud
Every template includes a selection of preset object styles—sets of attributes like colors, borders, and shadows—that are designed to look good with the template. A quick way to change how an object looks is to apply one of the preset object styles to it.
Select an object.
Depending on the type of object you selected, click one of the following tabs at the top of the Format sidebar on the right:
An image, shape, or text box: Click the Style tab.
A chart: Click the Chart tab.
A table: Click the Table tab.
Click one of the preset object styles near the top of the sidebar.
