For example: I want all odd numbered rows with white background, and all even numbered rows with a light green background.
Menu: Format->Styles and Formatting
Result style, right-click and modify; Background tab, and chose light green color.
Selected the range of cells;
Menu: Format->Conditional Formatting
Checked Condition 1, changed Cell value is to Formula is,
Entered formula ISEVEN(ROW()), and changed Cell Style to Result.
Thanks.
