[Option] stickyHeaders_filteredToTop [Default] true [Description] 
Scroll table top into view after filtering (v2.16.2) This is needed when the user choses to filter the table which results in fewer rows than are currently visible in the browser viewport. So, the sticky header may still exist, but the table body may not be seen. Setting this option to true forces the original table header to scroll back into view.
