This is not correct.
Along the way in one of the 3.5 versions (if I'm not mistaken) Servoy introduced the 'labelFor' property.
Using this property (on a label type element of course) you can bind it to another element, for example a field.
Only thing here is that you'll need to have named elements in order to bind the label to another element.
In a tableview the label with labelFor property will replace the default OS header.
As this all can be quite some work in existing solutions, you might want to add the labels using the solutionModel on startup.
Big advantage here is that you can re-style, take the labels off simply by altering the method that adds all these labels.
Anyway, here some more background info where you also participated a long time ago
