Not sure I understand how the latter two suggestions differ, but the first
certainly requires a constructor function in the global namespace for every
class which is what I am trying to avoid. My way, the classes occupy their
own private namespace and even the "class" method is not global existing
only as a method of Table type.

I just used strings as an example, the table contents could be any type for
a generic list container.
