Started with Tobias's WP-Table Reloaded which I loved and have on my site: http://ipaimpress.com which went live end of 2011.
Now our new site sports the new and improved version TablePress. It is the same easy user experience, but cleaner and easier then the previous version. I am not sure how we would have handled our Members Profile on our site, out theme doesn't support an authors page and we had no way to display and even search for a member on our site.
See how nice it sets up at: http://internationalpress.org/ipa-members
I also love the roll over effect which you can turn on or off. Very sharp looking don't you think?
