$( document ).ready( function( $ ) { var table_data=null; $.ajax({ "url": 'arrays_short.txt', "success": function(json) { var tableHeaders; $.each(json.columns, function(i, val){ tableHeaders += "" + val + ""; }); $("#tableDiv").empty(); $("#tableDiv").append('' + tableHeaders + '
'); //$("#tableDiv").find("table thead tr").append(tableHeaders); table_data=$('#displayTable').dataTable(json); }, "dataType": "json" }); });

<body>
<div id="tableDiv"></div>
</body>
</html>
