Hi Dave

This is a great tutorial: thank you!

I'd love to see how you'd go about adding table functionality to Trix. It's something that many people have been looking for without success over the past few years (https://github.com/basecamp/trix/issues/539). 

I've tried looking at it myself (the Trix homepage at Github is useful), but my JavaScript skills aren't all they should be!
