用法示例：

PHPExcelService::setExcelHeader(['订单号','性别','电话','收货人姓名','收货人电话','收货地址','商品信息','总价格','实际支付','邮费','优惠金额','支付状态','支付时间','订单状态','下单时间','用户备注'])->setExcelTile('订单导出'.date('YmdHis',time()),'订单信息'.time(),' 生成时间：'.date('Y-m-d H:i:s',time()))->setExcelContent($export)->ExcelSave();

$export 为数组变量，变量格式为：

array(2) {[0]=>array(16) {[0]=>string(21) "wx2019071611093410001"[1]=>string(3) "男"[2]=>NULL[3]=>string(4) "1123"[4]=>string(11) "13055558888"[5]=>string(30) "上海 闸北区 城区 123123"[6]=>array(1) {[0]=>string(48) "无线吸尘器F8 玫瑰金礼盒版  [1 * 0.10]"}[7]=>string(4) "0.10"[8]=>string(4) "0.10"[9]=>string(4) "0.00"[10]=>string(4) "0.00"[11]=>string(12) "余额支付"[12]=>string(15) "2019/0716 11:09"[13]=>string(9) "待收货"[14]=>string(19) "2019-07-16 11:09:34"[15]=>string(0) ""}[1]=>array(16) {[0]=>string(21) "wx2019070209390010001"[1]=>string(3) "男"[2]=>NULL[3]=>string(6) "刘强"[4]=>string(11) "18092217410"[5]=>string(37) "北京市 北京市 东城区 1823号"[6]=>array(1) {[0]=>string(22) "测撒测试  [1 * 10]"}[7]=>string(5) "10.00"[8]=>string(5) "10.00"[9]=>string(4) "0.00"[10]=>string(4) "0.00"[11]=>string(12) "余额支付"[12]=>string(15) "2019/0702 09:39"[13]=>string(9) "待评价"[14]=>string(19) "2019-07-02 09:39:00"[15]=>string(0) ""}
