Custom columns in django_tables2

Question

I've had a search around for this but haven't had much luck so looking for a bit of help. I'm trying to add some extra columns to a table defined by a model, using function definitions in the model. Here's what my code looks like now:

# models.py
class MyModel(models.Model):
    my_field = models.TextField()

    def my_function(self):
        # Return some calculated value based on the entry
        return my_value

# tables.py
class MyTable(tables.Table):

    my_extra_column = tables.Column(....)

    class Meta:
        model = MyModel

# views.py
table = MyTable(MyModel.objects.all())
RequestConfig(request).configure(table)
return render(request, ....)

My question is can I access my_function in the entries passed to MyTable so I can show the result of my_function in the custom my_extra_column column? I assume I need to be using accessors, but I can't see how I can access the queryset data using this. Thanks!
