Hiding columns on the fly have the weird effect of centering the table body. I had to change the style for table.dataTable margin from "0 auto" to "0 0" to solve it.
Any reason I shouldn't use "0 0" for margins?
Can you please link to a test case so I can see what is happening.
Going to close this bug as I've not been able to reproduce the issue. If you can, please link to a test case.
