        function ExportToExcel(tableId) //读取表格中每个单元到EXCEL中
        {
            try {
                var curTbl = document.getElementById(tableId);
                var oXL = new ActiveXObject("Excel.Application");
                //创建AX对象excel
                var oWB = oXL.Workbooks.Add();
                //获取workbook对象
                var oSheet = oWB.ActiveSheet;
                oSheet.Columns(1).NumberFormatLocal = "@";//第1列转换成字符串
                oSheet.Columns(6).NumberFormatLocal = "@";//第6列转换成字符串
                var lenRow = curTbl.rows.length;
                //取得表格行数
                for (i = 0; i < lenRow; i++) {
                    var lenCol = curTbl.rows(i).cells.length;
                    //取得每行的列数
                    for (j = 0; j < lenCol; j++) {
                        oSheet.Cells(i + 1, j + 1).value = curTbl.rows(i).cells(j).innerText;
                    }
                }
                oXL.Visible = true;
                //设置excel可见属性
            }

                if ((! +'\v1')) { //ie浏览器
                    alert("无法启动Excel，请确保电脑中已经安装了Excel!\n\n如果已经安装了Excel，" + "请调整IE的安全级别。\n\n具体操作：\n\n" + "工具 → Internet选项 → 安全 → 自定义级别 → ActiveX 控件和插件 → 对未标记为可安全执行脚本的ActiveX 控件初始化并执行脚本 → 启用 → 确定");
                } else {
                    alert("请使用IE浏览器进行“导出到EXCEL”操作！");  //方便设置安全等级，限制为ie浏览器
                }
