Hi Jeff, I ended up writing my own version of CheckboxCell (rather, taking the code for it, and making my own class with modifications).
First change: I added a boolean field "disabled", and a setEnabled call. Second change: I redid render so it has 4 options (checked | unchecked x enabled | disabled) Third change: removed all the code for keeping track of its value, since my getValue and FieldUpdater take care of that. Result, a disable able CheckboxCell that behaves the way I expect it to. (The purpose of the graphic was to show how hiding col 2, the checkbox column, moves col 3, a non-checkbox column, since you didn't seem to understand why I consider the show / hide to be a bad thing.)
