Hiding and Unhiding Columns 

To hide a column, right-click on its column title and choose Hide from the context menu. The column disappears from the display.

To unhide a column, right-click on the title of the column to the right of where you want to insert the column, and choose Unhide from the context menu. Then select the column you want to unhide from the cascading menu of hidden column names, as shown in the figure below. The unhidden column will be inserted to the left of the column on which you right-clicked to open the context menu.

Because the unhidden column is inserted to the left of the displayed column on which you right-click, you cannot unhide a column to be the last column in the grid. To make it the last column, unhide it before the last displayed column, and then drag the last column to the left and drop it before the newly unhidden column.

When the grid has the focus, you can also hide and unhide columns by choosing View ® Fields from the main menu to open the Select Displayed Fields dialog, as shown in the following figure. Highlight the fields you want to hide in the Fields to Display list and click Remove, or highlight the fields you want to unhide in the Available Fieldslist and click Add. Click OK when you are done to close the Select Displayed Fields dialog.

MDM will not allow you to hide all the columns.
