This is not what NSFormatter does. How a cell is drawn is defined by
the cell. The content of the cell may be modified by a formatter, but
the formatter isn't required and doesn't draw anything.
do I create a separate subclass of NSFormatter, or can I make my
existing data class subclass from NSFormatter and then use the data
objects for both data and as the NSFormatter? It seems silly to have
to create separate objects just to do the formatting when I am
already storing the data objects in the table to begin with.
You can do whatever you like. A formatter isn't compulsory. Your data
objects can supply their data in whatever form makes sense. It's the
cell that draws it.
