Your test case HTML has div elements that are created by Datatables causing a duplicate set of Datatables elements to be created. It took awhile to figure this out

Maybe you just need fixedHeader: true instead of setting an offset. Like this:

Ya, I had just copied html in. Working 2 fulltime jobs, one I don't get paid for, so getting time to put up proper test cases is slim.
Here is a video

I really need to figure this out.

This is my updated test case, it works no problem. I am wracking my brain.

Obviously, it appears some other code is interfering. What, I don't know.

Figured it out. Some javascript from the template I am using to make the header sticky. Removed it, all Is well, except some pages it's not being "fixed"
