Unhide Column

 

The Format_Column_Unhide menu function unhides a hidden column in a worksheet. You must first move to the hidden column in order to unhide it; hold down the Ctrl key and then press G to bring up the 'goto' dialog and then enter a cell reference that includes the column you want to unhide, e.g. enter C1 to go to the third column or D1 to go to the fourth column.
