OK, thanks for the pointers. This confirms my suspicion that (a) there is no simple way to do it (as in cell based tables) and (b) that view based tables, despite some obvious advantages, are not to be considered to be the Holy Grail of Table Making - as Apple wants to make us believe. BTW: The delegate methods I had intended to use in my outline above turned all out to be disabled for view based table views.
