Question

在使用PHPEXCEl设置cakephp中的导出excel工作表的值时，我得到对未定义方法PHPExcel_Calculation :: __ getMatrixDimensions（）的调用

我的密码

$ type = PHPExcel_IOFactory :: identify（$ gst_file）;                 $ excel2 = PHPExcel_IOFactory :: createReader（$ type）;

            $excel2 = $excel2->load($gst_file);

            $excel2->setActiveSheetIndex(0);

            $excel2->getActiveSheet()->setCellValue('C11', 1500)
                ->setCellValue('D11', 100);



                ob_end_clean();

            header('Content-Type: application/vnd.ms-excel');
            header('Content-Disposition: attachment;filename="gstr_one_To.xlsx"');
            header('Cache-Control: max-age=0');

            header('Cache-Control: max-age=1');

            header ('Pragma: public'); 
            $objWriter = PHPExcel_IOFactory::createWriter($excel2, 'Excel5');

            $objWriter->save('php://output');
