The samples we used were:
- Responsive Data Tables by Chris Coyer
- Responsive HTML Tables by Jared Cunha
- Build a Responsive Table Using Only CSS by Michael Musgrove
- jquery.webks-responsive-table by Julian Pustkuchen
Give these a try by copying and pasting the CSS and scripts into a simple table, then check their HTML to see what has to be modified in your sample table. Then try adjusting for different screen sizes. And do a search for other solutions.
We will continue this group in September as the Web Design SIG. The afternoon session will be the new WordPress SIG. See you then.
