        $oExcel = new \PHPExcel();

            ]);
            $sheet->setCellValue('A1', $bigTitle);
        }

        // 设置标题 A1 B1 C1 ....
        $colIndex = 0;
        $fieldsMap = [];
        foreach ($titles as $key => $title) {
            $fieldsMap[] = $key;
            $sheet->setCellValue(chr(65+$colIndex) . $rowIndex, $title);
            $colIndex++;
        }

        // 设置内容 A1 B1 C1 ....   A2 B2 C2 ....
        $rowIndex++;

                $sheet->setCellValue(chr(65+$colIndex).$rowIndex, $value[$field]);
            }
            $rowIndex++;
        }

        if ($suffix == '.xlsx') {
            header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        } else {
            header('Content-Type: application/vnd.ms-excel');
        }
        header('Content-Disposition: attachment;filename="'. $filename .'"');
        $oWriter = \PHPExcel_IOFactory::createWriter($oExcel, 'Excel2007');
        $oWriter->save('php://output');
        $oExcel->disconnectWorksheets();
        exit;
