Move a matrix to the right

I am creating a project in which labels are generated automatically depending on a matrix.

The matrix contains notes from students and what I'm trying to do is create the labels automatically based on the notes in the matrix, that I have managed to do, but the problem is in the positioning.

I also create some labels automatically for the names of the students, but those of the notes are superimposed on the names and I can not move the matrix to the right for more dimensions that I put.

Deputy source and capture. This font is from the Performed action of the button which creates the labels of the names and notes

for(int i=0;i<calificacion.nombres().length;i++){
        nombre = new JLabel();
        nombre.setText(calificacion.getNombre(i));
        jpResultado.add(nombre);
        nombre.setBounds(20, 30*i, 50, 20);
        nombre.setVisible(true);

    }
        for(int i=0; i<calificacion.notas().length;i++){
            for(int j=0; j<calificacion.notas()[i].length;j++){
                 calificacion.getNota(i, j);
                 System.out.println("Notas : " + calificacion.getNota(i, j));
                 notas = new JLabel();
                 notas.setText(String.valueOf(calificacion.getNota(i, j)));
                 jpResultado.add(notas);
                 notas.setBounds(70*j, 30*i, 50, 20);
                 //notas.setLocation(30*k, 20*j);

            }
        }
      this.pack();

As you can see in the image, everything is on the left and I can not position it further to the right
