javascript - Fixed table header with responsive table not working

I'm trying to fix my table header once it is scrolled down that it fixed at the top position.

I've managed to fix the header by making a javascript to detect the scroll position and then apply css to make the position as fixed at the top

But the column sizing of the header bee lost, apparently it bee smaller.

I will appreciate if someone able to help on this?
