to conditionally specify certain behaviour.

=head1 BUGS

This documentation is incomplete.

_Tableborder is just a _Table now.  _Tableborders should scroll (but not the
headers) and need and need more decoration. (data in white section ala gtksql
and sliding field widths) headers should be buttons that callback to sort on
their fields.

There should be a persistant, per-(freeside)-user store for window positions
and sizes and sort fields etc (see L<FS::UI::CGI/BUGS>.

Still some small bits of widget code same as FS::UI::CGI.
