To sort a column hover the mouse over the column header and click the two triangles on the far left side of the cell.
The first click will sort text columns A -> Z and numeric columns Smallest -> Largest.
The second click will sort text columns Z -> A and numeric columns Largest -> Smallest.
The third click will negate the sort and return the column to its initial state. The user must negate the sort if they wish to sort a second column in that table.
