How to make an a responsive table grid with alphabetical ordered columns

Outstanding and infinitely more elegant than my hacky solution for alphabetical table grids in Ember (I always try to SEO-up my comments here for the future guy like me trying to figure all this out :blush:).

Interestingly I just discovered the resizing bug and was afraid what it was going to do to my week. Greatly appreciate you taking the time.

Would I be able to on the component similar to the push answer here to get the dynamic array working?
