colNum is not increased when header has js-sort-none class and when you later sort the table it gets value from wrong column

Thank you. That bug appears to have been added in https://github.com/stationer/SortTable/issues/5.

It should be easy to fix as https://github.com/stationer/SortTable/pull/7/files?diff=unified&w=1.

I didn't test this yet, so I didn't merge it yet, but it looks straightforward.
