title: sorting datatable based on column index not name of column
body: <p>I have a DataTable which has 10 columns, I would like to sort the table by a column index 10 from largest to smallest. I know this should be easy for some but this is my first time using such a DataTable</p>
  
  <p>all the website that i have found all say that you have to know the column name but i dont have that and would like to make reference to the column by the index value of the column. which should sort all the rows in that datatble</p>
