menubarnb only is called within a cell that is already set to tcat so it should be an empty class cause if we set it to tcat as well then you would have double gradient calls on class's with background images. Your empty cell should follow the already called tcat parent class of the table cell
it does on every vb
system I see example here
here is the menubar template on this very photopost gallery here you look at
and notice in bold how the td is already set to tcat so the empty style classes in the table for menubar make no difference since style class is always going to fall back on the td it is in if nothing else is defined.
