Hover your mouse cursor over the grey box in the top left corner of the worksheet where row and column labels meet, then slowly move to the right until you see two vertical lines with arrows pointing out on each side <-||-> when you are over the join between the corner box and column C. At that point click and hold your left mouse button and drag to the right to widen the width of column A.

Alternatively, click the grey box in the top left corner of the worksheet where row and column labels meet to select ALL rows and columns, then select Unhide columns from the menu. (Note that this will unhide any hidden columns, rather than just A & B)
