You color a column or a column group by selecting Background color in the column menu in Edit table setup. Colors make it easier to find important columns again, for example Final Forecast.
How to do it
Click Table setup at the top of the table.
Open the menu (three dots) in the column header. For a column group, you select the color in the column group window.
Select Background color and click a color.
Click Save setup.
Good to know
To remove the color, select Background color again and click the no-color icon.
The color is saved in the table profile. If you share the profile, your colleagues see the same colors.
