It is possible to do some subclassing so that your cell contains an
NSTableView or other views.
However, this can have very serious performance implications. How
many items do you have in this overall table? Because once you start
getting into the mid double figures, you're going to have a lot
NSViews in you window, and Apple recommends a maximum of around 100
per window.
In your case though, it sounds like it would be relatively easy to
subclass NSTextFieldCell so that it draws a list of values.

Hi,
I need to implement a table cell that will display an arbitrary number
(well, zero to five or so) of items in a list as the "value" in a
column. (I'm obviously planning on using the new variable height
capability of NSTableView.)
My question is what approach should I take to implement the cell. I'm
thinking an override of NSCell is an obvious starting point, and I
need the capabilities of NSMatrix (or maybe even an embedded
NSTableView) to render the cell. What's not clear to me is
Am I on the right track? Is there sample code out there that
implements anything like this?
Thanks for this and all the other help I've found on the list.
