Add a method to your form that returns a list (or iterator over a
sequence) of tuples or lists containing all the information you need for
each row. You'll have to tell your form about the model and messages,
but that isn't so odd, since it already needs to know some of that in
order to generate the right number of fields.
So, for example, this method might return a list of tuples like
(BoundField instance, message_sender, message_title). You loop over this
list:
{% for field,sender,title in form.get_data %}
{{ field }} | {{ sender }} | {{ title }}
{% endfor %}
