[brandonkelly]

Fixes #55

Thanks, @brandonkelly. I got this patched up in some other work already but thanks for shooting over the PR. If you get inspired just shoot me a message if you'd like to make sure we don't double up on efforts. ;)

The table defaults code wasn't in my patch though. So I'll work that in manually if you're good with that.

@erikreagan sure feel free to use the Default Values change.
