The attributes are placed on <th> elements, for usability, which doesn't
work with our existing selectors unless you use a complicated combination
of :matches(), the subject indicator, and the column combinator (and that's
a very stretched definition of "existing selectors").

Its also trickier to do ascending/descending, since you'd have to use a
substring attribute match against "reverse".
