I am trying to sort my data table based on custom requirement where I need to push the null/empty values to bottom.
I have created data table where there are columns Age and Salary where I kept data empty in some rows. When ever user clicks on Age or Salary column null values should always stay at bottom for asc or desc sort. I have used method and override sort with
$.fn.dataTable.ext.oSort

I provided Link below for my Test Case with Data.
