Am I missing something here? Where are you building a table -- I don't see
any calls to TABLE(), just TR(). Also, I'm not sure about your syntax. It
looks like you are passing a tuple of TD's to TR instead of passing the TD's
as separate arguments (i.e., there's an extra set of parentheses inside TR).
Finally, what is 'trs[] =' doing -- I think that will raise a syntax error.
You should be able to create a table object (e.g., table = TABLE()), and
then append TR's to it via append -- e.g., table.append(TR('cell 1', 'cell
2')).
