如何通过PhpOffice/PhpSpreadSheet的分组/级别过滤从xlsx-file中获取可扩展行？

composer require phpoffice/phpspreadsheet

use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Reader\Xlsx;
use PhpOffice\PhpSpreadsheet\Worksheet\RowIterator;

$spreadsheet = IOFactory::load('path/to/your/file.xlsx');

$worksheet = $spreadsheet->getActiveSheet();

$worksheet->setAutoFilter('A1:Z1');

$iterator = $worksheet->getRowIterator();
$expandableRows = [];
foreach ($iterator as $row) {
    $cellValue = $worksheet->getCell('A' . $row->getRowIndex())->getValue();
    if ($cellValue !== null && $cellValue !== '') {
        $expandableRows[] = $row->getRowIndex();
    }
}

foreach ($expandableRows as $rowIndex) {
    $rowData = $worksheet->rangeToArray('A' . $rowIndex . ':Z' . $rowIndex, null, true, false);
    print_r($rowData);
}
