That was a very helpful example. Thank you. So using the web2py TABLE helpers
is best used for creating simple, static tables where the rows aren't
generated? I guess that's ok, I always thought that the controller was meant to
get the data, while the views format the data. But if the web2py way is to
format in the controller and make the views contain as little Python code as
possible, then that's they way I'll write it.
