Try moving the cursor slowly over the Column B heading towards the left side
of the Column Header until it changes shape to a parallel line with outwards
pointing arrows.

When it does, left click and drag to the right to unhide Column A.
(Hopefully)

Column A is hidden, and all panes are unfrozen. Even if I select ALL rows
&
columns, choose unhide and unfreeze, column A is still hidden. How do I
fix?
