Configuring Column Settings
By default on every page all columnar information is displayed but on certain pages where a large number of columnar information is available, all the columns cannot be displayed. It is also possible that some content may not be of use to everyone. Using column settings, you can configure to display only those numbers of columns which are important to you.
To configure column settings, click Select Columns and select the check box against the columns you want to display and clear the check box against the columns which you do not want to display. All the default columns are grayed and not selectable.
