Perhaps it is a better idea to assign the Define_Columns in the Views of
you zTable zclass definition (it is a separate tab in the management
interface there). You can assign any tab name there to any method in you
zclass. 

But I'm not sure I understand this correctly

Are they by any chance nested ZClasses? If so, this is a known problem.
If not, it is not entirely clear what you're doing. In general, if you
create a ZClass instance to make it appear in the target you intend, it
is important to do so through calling it through a
manage_addProduct['yourclass'].<yourclass>_factory and _not_ directly
through the <yourclass>_add method.

But once again, it is not entirely clear to me what you try to do
