Not tested, but another option would be to keep something like your current
code (though you can simplify by creating just a single version of the SPAN
code and fill in the color via a lookup in a dictionary, as in my previous
example), but instead of setting style attributes in your represent
functions, just set CSS classes (e.g., SPAN(value, _class='green-cell')).
Then use jQuery to set the background colors of the table cells:
$('.web2py-table td .green-cell').parent().css({background: "green"});
