Table - visible columns

Is it possible to catch an event when visible columns are changed with the little context menu in the table header? The feature is really nice but I need to be able save it in the db so the user doesn't have to change it all over everytime he/she logs in. It is obviously possible to make some sort of save config link but it would be neater to do it automatically upon change.

Cheers

The question has been addressed in this thread.

Intercepting column visibility changes should be possible by overriding one method in Table.
Intercepting column order changes when they happen is not easy, but you could ask the table about the visible columns and their order e.g. when closing the view with the table.
