A Long expression that specifies the index of the column, or A String expression
that specifies the name of the column to un-split it.
The UnsplitCell method unsplits the cell. The SplitCell method splits a cell in two cells ( the newly
created cell is called inner cell ). Use the InnerCell property to get the
inner cell. Use the CellParent property to
get the parent of the inner cell. The CellParent
property gets 0 if the cell is not an inner cell. The parent cell is always
displayed to the left side of the cell. The inner cell ( InnerCell ) is
displayed to the right side of the cell. Use the CellWidth
property to specify the width of the inner cell.
