Read class from th on every dataTable instance

Newcoma

Hello

I'm trying to get dataTables to initialize with options based on classes on the th. So I can in this example get option values into "aoColumns". But It does only work when I have one table instance.

As seen here

How do I make it work with multiple tables ?
