Thanks for the feedback.
Yes, the field names are different for each model and that is why I
asked the question. I had solved the problem with your suggestion #2:
"Create base template and extend that with model specific templates."
But I did not find this to be a very efficient way to solve the
problem since a model specific template is needed for each model and I
was hoping that Django may have an easier solution that I missed in
the documentation.
Con of this approach: If a field is added/deleted from a model, a
change is needed to the template.
Pro: But it is also allows the custom display of individual models.
It would be cool to see a ModelTable class added within Django (I
guess I could always write one myself too!) that would allow table
data to be displayed with field headers and allow columns to be
sortable.
