I'm not very familiar with tabulated lists, but this seems like it's
fixing the problem you're seeing...

This might be more controversial, though.  I think it looks nice, but
some people don't like so many lines.  Perhaps it should be a defface,
so that people can change this themselves?  The default could be what
you're describing, though.
