How to split column "B" and "C" vertically and mark column "I" of the right
pane of the worksheet as a first column? Microsoft's sources I came across
say that: "You cannot split panes and freeze panes at the same time. When you
freeze panes within a split pane, all rows above and columns to the left of
the selection will be frozen and the split bar will be removed."
Is it possible anyway?
