Show Ratings according to PHP MYSQL subject

Good morning Community. I have this student report card by subject But I have tried to make the notes go horizontally according to the subject and not vertically according to the image. I have not been able to solve this concern.

The code I occupy is

class Consultar_Materias extends Conexion{
    private $consulta;
    private $fetch;

    function __construct($codigo){
        parent::__construct();
        $this->consulta = $this->conexion_db->query("SELECT * FROM materia WHERE id='$codigo'");
        $this->fetch = mysqli_fetch_array($this->consulta);
    }

    function consultar($campo){
        return $this->fetch[$campo];
    }
}

this code is the one on the page:

if(!empty($_GET['cod']) and !empty($_GET['periodo'])){
    $id_periodo=$_GET['periodo'];
    $id_alumno=$_GET['cod'];
    $oPeriodo=new Consultar_Periodo($id_periodo);
    $oAlumno=new Consultar_Alumno($id_alumno);  
    $nombre_alumno=$oAlumno->consultar('nombre');

    $oGrado= new Consultar_Grado($oAlumno->consultar('grado'));
    $oSalon= new Consultar_Salon($oAlumno->consultar('salon'));

    $nombre_salon=$oSalon->consultar('nombre');
    $nombre_grado=$oGrado->consultar('nombre');

    $oEmpresa= new Consultar_Empresa('1');

    $dir='Direccion: '.$oEmpresa->consultar('direccion').'<br>'.$oEmpresa->consultar('pais').' - Viña del Mar';

    $regresar=$oAlumno->consultar('salon');#5
}else{
    header('Location:error.php');
}
</table>
      <br />
      <table width="90%" rules="all" border="1" style="font-family:Arial, Helvetica, sans-serif">
      <tr>
        <td>
            <center><strong>Nombre del Alumno</strong><br /><?php echo $nombre_alumno; ?></center>
        </td>
        <td width="25%"><center><strong>Curso</strong><br /><?php echo $nombre_grado; ?></center></td>
        <td width="25%"><center><strong>Sala<br /></strong><?php echo $nombre_salon; ?></center></td>
      </tr>
      <tr>
        <td colspan="3"><br /><center><strong>Informe del Periodo <?php echo $oPeriodo->consultar('nombre'); ?> Semestre</strong></center></td>
      </tr>
      </table>
      <bR />
      <table width="90%" rules="all" border="1" style="font-family:Arial, Helvetica, sans-serif">
      <tr>
        <td width="50%"><strong><center>Materia</center></strong></td>
        <td width="50%"><strong><center>Calificación</center></strong></td>
      </tr>
      <?php 
        $pa=mysqli_query($conexion,"SELECT * FROM notas WHERE alumno='$id_alumno' and periodo='$id_periodo' ORDER BY materia");             
        while($row=mysqli_fetch_array($pa)){
            $oMateria=new Consultar_Materias($row['materia']);
      ?>
      <tr>
        <td><center><?php echo $oMateria->consultar('nombre'); ?></center></td>
        <td><center><?php echo $row['valor']; ?></center></td>
      </tr>
      <?php } ?>
    </table>

How can I put each grade horizontally according to each subject?

Mathematics | 40 | 50 | 60 | 70 |

Language | 55 | 60 | 60 |

Thanks
