I spent many hours looking for a tables plugin that would provide the tables functionality I was looking for. I tried dozens of different plugins, but this is the only one that would accomplish the responsive behavior I needed. In fact there were a couple of additional things I was trying to customize, and when I wrote to the author of this plugin, he went ahead a coded my requests into the plugin.
I highly recommend this plugin to anybody who needs to create tables that are able to reformat in a visually pleasing way when viewed on mobile devices. It works great, and the author support is excellent. 5 stars!
