Resizing the columns is easy.  Here's how:

1) Move the cursor over a column line in the column title area.  You'll see the cursor change. 

2) When the cursor changes, hold down on the mouse button and move the column line to a new location.  In the example below, the right side of the column Hr Rate is being moved to make the column larger.

3) Release the mouse button.  That's it!

           If the column will not enlarge, increase the document window size, 
              and try again.
