我想求和earning代码末尾的列值与总计。我在用Jquery datatable通过此代码过滤记录，但无法编写总计代码。我也tried footer callback of datatable但没有得到想要的结果。

<script type="text/javascript">
$(document).ready(function(){
$.datepicker.regional[""].dateFormat = 'dd/mm/yy';
$.datepicker.setDefaults($.datepicker.regional['']);
$('#example').dataTable({

aoColumns: [ { type: "hidden" },

],
"fnFooterCallback": function ( nRow, aaData, iStart, iEnd, aiDisplay ) {
/*
* Calculate the total market share for all browsers in this table (ie inc. outside
* the pagination)
*/
var iTotalMarket = 0;
for ( var i=0 ; i<aaData.length ; i++ )
{
iTotalMarket += aaData[i][11]*1;
}
/* Calculate the market share for browsers on this page */
var iPageMarket = 0;
for ( var i=iStart ; i<iEnd ; i++ )
{
iPageMarket += aaData[ aiDisplay[i] ][11]*1;
}
/* Modify the footer row to match what we want */
var nCells = nRow.getElementsByTagName('th');
nCells[1].innerHTML = parseInt(iPageMarket * 100)/100 +
'% ('+ parseInt(iTotalMarket * 100)/100 +'% total)';
}
});
});
