Applying Font, Color, and Borders to Cells
Styles can save a lot of time when formatting a spreadsheet. A style is a unique collection of font attributes that include number, alignment, font, border, patterns, and protection. Many different styles can be created in a spreadsheet, each with different attributes and names. When applied to a cell, information in it resembles the attributes defined for that style.
You can change the style attributes for any style name.
You can create new styles by clicking the Add button in the Style dialog box.
