I have a table with checkboxes in my application. However, they only show information from my model and letting the user check or uncheck them doesn't make sense.
Unfortunately, TableColumn doesn't have setEnabled method. I've tried to wrap the table into an extra Composite and call setEnabled(false) on it, but this prevents me from scrolling the table as well.
Is there a way to do this?

I just recognize that on the jface-level a solution seems possible by
defining a ICheckStateProvider implementation. You could check-out what
this implementation does internally to realize the same on the pure
SWT level.

Actually, I am using an ICheckStateProvider on a CheckboxTableViewer, and this doesn't disable toggling checkboxes. Am I missing something?
After thinking some more, I can use ICheckStateListener...
