You can have Spread automatically merge cells between columns or between rows if
the cells have the same value based on the policy that you set.
The component can automatically combine cells that have the same contents. You might
want to do this, for example, when bound to a database, as shown in the figure below
where the cells in the Year column merge where the year value is the same, as with
1995 and 2003.
Merging is an automatic feature. You tell the component which columns and rows allow
cells to be combined automatically, and any cells within that set that have the
same contents are combined for you. You can have the cells in the specified row
or column combine the cells automatically, or only combine them if the cells to
their left (in columns) or above them (in rows) are merged.
