I forked thin library and kept the same behavior and apis, if you are curious about migrating to something a little more maintained

@NullVoxPopuli yes, I'm eager to try! last time I stopped at unpublished npm package, (which I now see that is now resolved), and at the need of patching Reordering hidden columns. I'll try again, thanks!

Also, see universal-ember/table#68, which I found interesting.

Would you be willing to apply your patch in a pr? <3

@NullVoxPopuli ok, I ported the PR here: universal-ember/table#74. There may still be some unanswered questions from the original PR (and three skipped tests), but I've used it with success in practice at least.
