Adding Mixin to Table subclass generates metaclass conflict #972

if I have a Mixin

class A_Mixin(metaclass=DeclarativeColumnMetaclass)
pass

and a table class

class B_table(A_Mixin, tables.Table):
pass

I get the typeError:metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of athe metaclasses of all its bases.

My goal with this approach was to create a mixin to reuse throughout the app for table definition.
