Column settings are used to select the types of information which are displayed on a certain page. Some pages have a large amounts of information is available and not all content can be displayed on a single screen. Also, some pages may contain content that is not of use to you. Using column settings, you can display only that content which is important to your requirements.
To configure column settings, right-click the header of a column and select Column Settings. Any changes that you make to the column settings of a list are stored in the unit’s configuration and will display the next time that you access the list.
To return a page’s columns to their default state, select Reset All Columns, located at the bottom of the Column Settings menu.
