title: How to calculate average of 5 student mark, and implement that in datatable.js, how to do this?
body: <p>This is my json data</p>
  
  <pre><code>var myList = [
      [1, "Karthick", 90, 95, 85, 95, 100,],
      [2, "Ram", 98, 90, 95, 95, 100],
      [3, "Suthan", 80, 90, 85, 100, 95],
      [4, "Ganesh", 90, 100, 100, 99, 96],
      [5, "Thilak", 98, 99, 99, 100, 100],
      [6, "Mari",90, 100, 100, 99, 100]
  ]; 
  
  $(document).ready(function() {
      $('#demo').html( '&lt;table cellpadding="0" cellspacing="0" border="0" class="display" id="example"&gt;&lt;/table&gt;' ); 
      $('#example').dataTable( {
          "data": myList,
          "columns": [
              { "title": "Id" },
              { "title": "Name" },
              { "title": "Mark1" },
              { "title": "Mark2"},
              { "title": "Mark3"},
              { "title": "Mark4"},
              { "title": "Mark5"},
              { "title": "Average"},
              { "title": "Grade"}
          ]
      });   
  });
  </code></pre>
  
  <p>I send those json data in to datatable.js, but my doubt is how to calculate the average of 5 marks and show that average mark in datatable using datatable.js</p>
