Solution 1:

You need to create a custom field with an extra colspan attribute.

First define the custom field sub classing TextField:

classMyCustomTextField(TextField):def__init__(self, colspan=4, *args, **kwargs):
        super(MyCustomTextField, self).__init__(*args, **kwargs)
        self.colspan = colspan

Now use the custom field in your form:

classMyForm(Form):
    my_field = MyCustomTextField(4, u"Enter a number", validators=[Required('This Field is Required')])

See that first parameter (a 4 in this case) for MyCustomTextField? That's your colspan attribute.
