To add or remove any column, choose "Manage Columns" under the down arrow that shows on the right side of any column when you mouse over it. A dialog box will appear showing the names of every available column. You can select or unselect any column, or use the 6-dot icon to rearrange the order of the columns.
You can also rearrange columns by just clicking and holding the title of any column and moving it to the location you want.
