Automatic Responsive Tables

Just tested this with a Donation Confirmation Receipt from our Give plugin and it works perfectly without having to configure anything. 
I don't know what it would do with really complex tables, but for the basics this does the job.
Nice work!



Works right out of the box

Leave your tables as they are. Add this plugin, and they're all responsive.
