Thanks Chris, that worked great!
Here's my new class:
class MyTableForm(widgets.TableForm):
params = ['extra_template_vars']
extra_template_vars = {}
def update_params(self, params):
params.update(params.get('extra_template_vars', {}))
super(MyTableForm, self).update_params(params)
Updated controller code:

I may move the form instantiation out of the controller now also.
Cheers,
Steve
