Hi I am not getting the default arrows for the sorting columns. I am using <apex:includescript value="//code.jquery.com/jquery-1.11.1.min.js" / >
<apex:includescript value="//cdn.datatables.net/1.10.4/js/jquery.dataTables.min.js" />
<apex:stylesheet value="//cdn.datatables.net/1.10.4/css/jquery.dataTables.css" />

<apex:stylesheet value="{!URLFOR($Resource.Jquery_sumo_select, '/sumoselect.css')}"/>
<apex:includeScript value="{!URLFOR($Resource.Jquery_sumo_select, '/jquery.sumoselect.min.js')}" />
