[web2py] Syntax Error when compiling html helpers with attributes

[mwolfe02]

I receive the following traceback when trying to run some pretty 
straightforward code:

Traceback (most recent call last):
  File "M:\My Documents\EstateCommander\web2py\gluon\restricted.py", line 208, 
in restricted
    ccode = compile2(code,layer)
  File "M:\My Documents\EstateCommander\web2py\gluon\restricted.py", line 193, 
in compile2
    return compile(code.rstrip().replace('\r\n','\n')+'\n', layer, 'exec')
  File "C:/Users/Mike/Documents/My 
Dropbox/EstateCommander/web2py/applications/estate/controllers/forms.py" 
<http://127.0.0.1:8000/admin/default/edit/estate/controllers/forms.py>, line 15
    table = TABLE(*rows, _border='0', _align="center", _width="50%")
                               ^
SyntaxError: invalid syntax


This is only an error on Windows.  The code runs fine on CentOS 
(Webfaction).  Am I missing something here?

Here's the full context of the erroring line in case that might help:

    # create a small table with some data:
    rows = [THEAD(TR(TH("Key",_width="70%"), TH("Value",_width="30%"))),
            TBODY(TR(TD("Hello"),TD("60")), 
                  TR(TD("World"),TD("40")))]
    table = TABLE(*rows, _border='0', _align="center", _width="50%")
