The Excel Table Styles give a user a choice of different styles ranging from Light, Medium and Dark.
There are over 50 choices depending on your favorite style or company standard but you are not only limited to those.
You have extra Table styles in the Page Layout tab in your Ribbon menu. Click on that and select the Colors drop-down and you can choose from an array of combinations.
Go crazy with this to brighten up your dull data 🙂
