Calc comes with a few built-in cell and page styles to improve the appearance of your spreadsheets and reports. Although these built-in styles are adequate for many uses, you will probably find it useful to create styles for your own frequently used formatting preferences.

Click Format › Styles › Styles and Formatting or press F11.
At the top of the panel Styles and Formatting, click either Cell Styles (a green cell) or Page Styles (a document).
Right-click anywhere in the list of styles in the panel Styles and Formatting. Then click New.
Specify a name for the style and use the various tabs to set the desired formatting options.
When you are done configuring the style, click OK.
Procedure 11.2: Modifying a Style
Click Format › Styles › Styles and Formatting.
At the top of the panel Styles and Formatting, click either Cell Styles (a green cell) or Page Styles (a document).
Right-click the name of the style you want to change, then click Modify.
Change the desired formatting options.
