Заголовок сетки перемещается при прокрутке в браузере IE11, но не в chrome и более низких версиях браузера IE?

Question

WebUIGrid. css. Класс WebUIGrid_FixedHeaderClass связан с заголовком сетки.

 WebUIGrid_FixedHeaderClass class is associated with Grid Header.

        "WebUIGrid_FixedHeaderClass" class of grid header.
        .WebUIGrid_FixedHeaderClass {
            position: absolute;
            z-index: 9999999996;
            table-layout: fixed;
        }

WebUIGrid. js. Метод setupFixedHeader () вызывается во время scrolling.Grid заголовок создается динамически и присоединяется к контейнеру. С таблицей связан класс сетки "WebUIGrid_FixedHeaderClass". Это проблема IE11.objFixedHeader является идентификатором GRID. Тот же код работает в chrome и более низкой версии IE

    setupFixedHeader() method is called while scrolling.Grid header is created dynamically and attached to container.Grid class "WebUIGrid_FixedHeaderClass" is associated with table. 
Is it issue of IE11.objFixedHeader is the ID of GRID. Same code is working in chrome and lower version of IE.

                function setupFixedHeader(id)
                    {
                        var objRef = webUIClientLibrary.getObjRef(this, id);
                        if (objRef.allowFixedHeader) {
                            var ctlTable = objRef.getMainTableCtl(id);
                            if (ctlTable != null) {
                                var ctlHeaderRow = objRef.getMainTableHeaderRowCtl(id);
                                if (ctlHeaderRow != null) {
                                    // If the fixed header table does not exist, create the object - hidden at first.
                                    var idFixedHeader = id + "_FixedHeader";
                                    var idFixedHeaderRow = idFixedHeader + "_0";
                                    var objFixedHeader = null;
                                    if (document.getElementById(idFixedHeader) == null) {
                                        $("#" + ctlTable.id).after("<table id='" + idFixedHeader + "' class='WebUIGrid_FixedHeaderClass' cellpadding='0' cellspacing='0' border='0'" +
                                            ((objRef.controlWidth == "") ? "" : " width='" + objRef.controlWidth + "'") + ">" +
                                            webUIClientLibrary.replace(ctlHeaderRow.outerHTML, ctlHeaderRow.id, idFixedHeaderRow) +
                                            "</table>");
                                        objFixedHeader = $("#" + idFixedHeader);
                                        objFixedHeader.hide();
