(Looked at a bunch of answers on this topic, none of which applies to this question.)

The DataTables have the feature of letting the user click on each column's Up/Down triangle icons to sort in Ascending or Descending order. I have loaded the data as follows

        oTable.fnAddData( ["Bogus data","1,541,512","12.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","3,541,512","2.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","541,512","1.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","2,541,512","32.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","741,512","3.5%","0","0","0"]);

        oTable.fnAddData( ["A Bogus data","41,512","1.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","2,541,512","12.5%","0","0","0"]);

        oTable.fnAddData( ["Z Bogus data","1,541,512","12.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","3,541,512","2.5%","0","0","0"]);

        oTable.fnAddData( ["La Bogus data","541,512","1.5%","0","0","0"]);

        oTable.fnAddData( ["The Bogus data","2,541,512","32.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","741,512","3.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","41,512","1.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","2,541,512","12.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","1,541,512","12.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","3,541,512","2.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","541,512","1.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","2,541,512","32.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","741,512","3.5%","0","0","0"]);

        oTable.fnAddData( ["Bogus data","41,512","1.5%","0","0","0"]);

In column number 2 the numeric values are processed alphabetically when I click on the Up/Down triangles. How can I adjust it so that the second column Up/Down arrows will trigger the proper way, treating the characters as numbers. I tried using the following initialization:

oTable = $('.utable').dataTable( {

"aoColumns": [{ sWidth: '60%' },{sWidth: '30%', "sType": "numeric"},{ sWidth: '10%' }],

"sDom": 'rt',

"sScrollY":"200px",

"bPaginate":false,

"bFilter":false,

"bInfo": false});  

All this does is to lock the colum and the Up/Down icons will not work in the header of that column.
