    I might be missing it but I don't see where you are initializing Datatables in the attached code.

    Cannot read property 'length' of undefined

    This could be due to the Datatables config referencing a column index that is not in the table. Without seeing the problem and what the generated tables look like its hard to diagnose. Can you post a link to your page or a test case replicating the issue?
