如何使用此回显函数分配变量

Question

echo“”;为（$ row = 1; $ row <= $ lastRow; $ row ++）{

        echo "<tr><td scope=\"row\">";
        echo $worksheet->getCell('A'.$row)->getValue();
        echo "</td><td>";
        echo $worksheet->getCell('B'.$row)->getValue();
        echo "</td><td>";
        echo $worksheet->getCell('C'.$row)->getValue();
        echo "</td><td>";
        echo $worksheet->getCell('D'.$row)->getValue();
        echo "</td></tr>";
    }
    echo "</table>";
