You're confusing the Model, View, and Controller.

To put a button in a table cell, you have to add a button control to the View definition. But you're attempting to add it to the Model definition.

In MVC, the View and the Model both have trees that mirror each other's structure. Except that in the View tree, you have the control definitions and in the Model tree, you have their corresponding data values.

Unfortunately, this isn't something that I can explain briefly. However, there are a lot of good Computer Science books that explain how MVC works, since it's the basis of almost all modern-day GUIs.

I think I recall seeing some J2ME tutorials on the Sun website that had dropdown menu controls in table rows. Or it may have been in the regular JDK Swing tutorials.
