Resizing List Columns
You might find that you want to change the width of a column so that you can see all of the data in the column. A changed column width is automatically saved, so you do not have to repeatedly resize the column.
To resize columns
Place the cursor over the column divider of the column you want to resize.
A resize arrow appears.
Click to select the column divider and, without releasing the selection, move the column divider out to widen the column or in to narrow the column.
