On a side note - note that for "flags" you can :

$table2->attach($window, 0, 1, 0, 1, ['fill', 'expand'], 'shrink', 1, 1);

E.g. when a flags param has only one element, the scalar notation
is allowed.

Well it needs additional code, and having too many ways to do the
same thing is mostly confusing for people who read code examples
and code excerpts.. that's why I didn't allow the '-something'
notation when I coded the enums/flags stuff.
