Helpers are callable objects that take arguments, and you cannot use an if
statement as an argument in Python. However, you can use a conditional
expression, so the following should work:
*[TR(TD(row.DBQuery.ExampleName), _class='Test1' if row.DBQuery.Value==1
else 'Test2') for row in query]
See
http://docs.python.org/reference/expressions.html#conditional-expressions.
