Just to clarify the original problem, when a controller action returns a
dictionary (as in your original code), web2py assumes it should then look
for an execute a view. If a dedicated view does not exist for the action,
it will default to generic.html (though this is disabled by default, except
for local requests in the welcome app). So, you should either create a view
that generates the HTML you want based on what is returned in the
dictionary, or you should not return a dictionary.
Instead of a dictionary, you can directly return HTML as a string (which is
what your new code does) by applying the .xml() method to the UL helper.
However, you don't actually need to apply the .xml() method, because if you
return an HTML helper object, web2py will automatically serialize it to a
string for you.
As for returning an HTML table rather than a UL, there's no reason you
couldn't do that instead. Just create a TABLE object and return that.
