Compute a value from the javasript source dynamically and display the value using Jquery Datatable

krn1231

Is it possible to display an extra column under Jquery Datatables by name SubPrice and add sorting to it dynamically which is based on javascript source input values Total - Price in JSON ??

This is my javascript source

var json = [
  {
    "Name": "ONE",
    "Price": "12" ,
    "Total" : "120"
  },
  {
    "Name": "TWO",
    "Price": "100",
     "Total" : "500"
  },
  {
    "Name": "THREE",
    "Price": "42" ,
     "Total" : "300"
  }]




 $(function()
  {
    //$("#kiran").dataTable();
    //displayData();
 var table =   $('#kiran').dataTable(
    {
      "order": [
        [1, "desc"]
      ],
      "paging": false,
     "aaData": json,
      "aoColumns": [
        { "mDataProp": "Name" },
        { "mDataProp": "Price" }
    ]

    });

setInterval (function test() {
         table.fnDraw();
       }, 3000);

  })
