TableTools date range

Hi all,

I use TableTools, with download function and it's work.
When I use filters, it's good but I don't know why, when I use a date range filter, in my export, I don't have this filter.
However, the filter is working in my datatable.

Can you help me ?

Code JS

TableTools.BUTTONS.download = {
	"sAction": "text",
	"sTag": "default",
	"sFieldBoundary": "",
	"sFieldSeperator": "\t",
	"sNewLine": "<br>",
	"sToolTip": "",
	"sButtonClass": "DTTT_button_text",
	"sButtonClassHover": "DTTT_button_text_hover",
	"sButtonText": "Download",
	"mColumns": "all",
	"bHeader": true,
	"bFooter": true,
	"sDiv": "",
	"fnMouseover": null,
	"fnMouseout": null,
	"fnClick": function( nButton, oConfig ) {
		var oParams = this.s.dt.oApi._fnAjaxParameters( this.s.dt );
		var iframe = document.createElement('iframe');
		iframe.style.height = "500px";
		iframe.style.width = "1000px";
		iframe.src = oConfig.sUrl+"?"+$.param(oParams);
		document.body.appendChild( iframe );
	},
	"fnSelect": null,
	"fnComplete": null,
	"fnInit": null
};

$(document).ready(function() {
			// Affichage du tableau avec le détail des entrées
			$('#tabDetail').dataTable({
				"aaSorting": [[ 1, 'desc' ]],
				"bProcessing": true,
				"bServerSide": true,
				"sPaginationType": "full_numbers",
				"sDom": 'T<"clear">lfrtip',
				"oTableTools": {
					"aButtons": [{
						"sExtends": "download",
						"sButtonText": "EXCEL",
						"sUrl": "extranet/scriptPHP/csvGeneral.php"
					},{
						"sExtends": "download",
						"sButtonText": "PDF",
						"sUrl": "extranet/scriptPHP/pdfGeneral.php"
					}]
				},
				"sAjaxSource": "extranet/scriptPHP/serverSideGeneral.php",
				"fnServerData": function( sUrl, aoData, fnCallback ) {
					$.ajax( {
						"url": sUrl,
						"data": aoData,
						"success": fnCallback,
						"dataType": "json",
						"cache": false
					} );
				}
			}).columnFilter({
				aoColumns: [{ type: "text" },
					{ type: "date-range"},
					{ type: "time-range" , values: ["07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19"]},
					{ type: "select", values: ['muret', 'labarthe']}]
			});
		});
