如何只写入 active sheet 的 xlsx 文件 PHPSpreadsheet

Question

我想将 xlsx 文件显示为 html，但它总是 return 文件的第一个 sheet。我想要的是让作者仅在有多个 sheet 时显示一个活动的 sheet（sheet 的名称和顺序是随机的）。这是我的代码：

public function view_excel($path){
        $file = realpath(FCPATH)."/uploads/PKB/".$path;
        $reader = IOFactory::createReader('Xlsx');
        $spreadsheet = $reader->load($file);
        // $spreadsheet = $spreadsheet->getActiveSheet();
        $writer = IOFactory::createWriter($spreadsheet, 'Html');
        $message = $writer->save('php://output');
    }

有办法吗？谢谢

我成功做到了：

public function view_excel($path){
        $file = realpath(FCPATH)."/uploads/PKB/".$path;
        $reader = IOFactory::createReader('Xlsx');
        $spreadsheet = $reader->load($file);
        $active_sheet = $spreadsheet->getActiveSheet()->getTitle();
        $reader->setLoadSheetsOnly($active_sheet); //only load active sheet
        $worksheet = $reader->load($file);
        $writer = IOFactory::createWriter($worksheet, 'Html');
        $message = $writer->save('php://output');
    }

不得不加载文件两次
