Django 中的数据表修改列排序

Question

I write Django app, where I have a base.html template and I defined var table where I declared order by column 0 with 'desc' (look below) So I currently use it some templates, where I extend base.html. But now I need to sort in new template firstly by the second column, and after that by the first column (like this: "order": [1, 0, 'desc'] ). I don't know how I modify this variable without a duplicate code. Could somebody help me?

var table = $('#example').dataTable( {
  "columnDefs": [ {
      "targets": 0,
      "searchable": false,
      "order": [0, 'desc'],
      "ordering": true,
    } ]
} );

In template which extends 'base.html'

<script> 
     //modify order method
</script>

You can set the ordering using .order() then redraw the table:

table.order( [ 1, 'desc' ], [ 0, 'desc' ] ).draw();
