Yes, but you forgot to extend JList or JBoxList (whatever that is).
You would return this from the getTableCellRendererComponent method.
Of course, you would have to initialize the JList to whatever.
You also need to keep in mind that a cell renderer is just that: a renderer. It's like taking a screenshot of the component and drawing it into the table cell. It doesn't put an actual list component in the cell. So you aren't going to be able to just click on list items. You'd have to swap for a cell editor that is the same list to do that. Or do some fancy mouse event handling tricks.
It's a royal pain, but you might want to rethink doing it.
