Well you can check for an OnStateChange or an OnUpdate (events of your DataSource).
In these events you can check which record is active and then change the state of the table to what you want. I think OnStateChange is better then OnUpdate.
Haven't tried this out. But I think it's a good idea and should work.

You can also use the Before or After Insert, Edit Delete events of TTable component.
