For the first time I am trying to learn to work with tables but, reading manuals and videos, I can not understand much since almost all are in English.

My program is this, with the table added:

In the code, I only have this.

I declare:

private final JTable table;

Code of the table itself:

table =  new JTable();
        table.setBounds(10, 297, 445, 143);
        contentPane.add(table);

According to what I managed to understand, you have to create two arrangements:

arreglo1 [] = {"#", "origen", "destino", "duracion", "precio"};

arreglo2 [][] = null;

Being the 1st the title. So far I could not understand anything. I hope you can help me please. I am also interested in having a Scroll to be able to download and upload and view the data.

Good if you're right, you have to create two arrangements

1) for the headers (or column name) of your table

String[] columnas= {"#", "origen", "destino", "duracion", "precio"};

2) for the data in your table

String [][] data = {
                {"1", "Casa", "Trabajo", "20 minutos", "4000"},
                {"2", "Trabajo", "Casa", "30 minutos", "5000"}
};

Then you have your table

DefaultTableModel model = new DefaultTableModel(data, columnas);
JTable tabla = new JTable(model);

To add a scroll to your table

JScrollPane scroll = new JScrollPane(tabla);
scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); 
add(scroll);

Now to add different values to your table, as we have a model that is the order in which you want the data to be displayed

Object[] row = {"3", "Casa", "Playa", "50 minutos", "10000"};
DefaultTableModel model = (DefaultTableModel) tabla.getModel();

model.addRow(row);

EDIT

Do not add all your code because I do not have the classes or anything like that, I could not accommodate visually how you want to get the view, but this solves the problem. As the class extends of JFrame we give add to the elements and it is not necessary to create a panel.

public static void main(String[] args) {
    // TODO Auto-generated method stub
    GUI frame = new GUI();
     frame.pack();
     frame.setVisible(true);
}

public GUI(){
    JTextField txtNumeroOrigen;
    JTextField txtNumeroDestino;
    JTextField txtDuracion;
    JTextField txtPrecioTotal;
    JCheckBox checkboxProvincial;
    JCheckBox checkboxLocal;
    JCheckBox checkboxFranja1;
    JCheckBox checkboxFranja2;
    JCheckBox checkboxFranja3;
    JTextField txtTotalDeLlamadas;
    JTextField txtPrecioActual;
    JTable table;
    setTitle("Call Center");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 471, 480);

    JLabel lblTipo = new JLabel("Tipo:");
    lblTipo.setBounds(16, 30, 46, 14);
    add(lblTipo);

    JLabel lblFraja = new JLabel("Franja:");
    lblFraja.setBounds(125, 30, 46, 14);
    add(lblFraja);

    JLabel lblNmeroOrigen = new JLabel("N\u00FAmero Origen");
    lblNmeroOrigen.setBounds(200, 30, 108, 14);
    add(lblNmeroOrigen);

    JLabel lblNmeroDestino = new JLabel("N\u00FAmero Destino");
    lblNmeroDestino.setBounds(200, 55, 108, 14);
    add(lblNmeroDestino);

    JLabel lblDuracion = new JLabel("Duraci\u00F3n");;
    lblDuracion.setBounds(200, 81, 108, 14);
    add(lblDuracion);

    txtNumeroOrigen = new JTextField();
    txtNumeroOrigen.setBounds(318, 27, 130, 20);
    add(txtNumeroOrigen);
    txtNumeroOrigen.setColumns(10);

    txtNumeroDestino = new JTextField();
    txtNumeroDestino.setBounds(318, 55, 130, 20);
    add(txtNumeroDestino);
    txtNumeroDestino.setColumns(10);

    txtDuracion = new JTextField();
    txtDuracion.setBounds(318, 86, 130, 20);
    add(txtDuracion);
    txtDuracion.setColumns(10);

    Object[][] data = {
            {"1", "Casa", "Trabajo", "20 minutos", "4000"},
            {"2", "Trabajo", "Casa", "30 minutos", "5000"}
     };
     //array de String's con los títulos de las columnas
     String[] columnNames = {"#", "origen", "destino", "duracion", "precio"};
     //se crea la Tabla
     table = new JTable(data, columnNames);
     //table.setPreferredScrollableViewportSize(new Dimension(500, 70));
     //Creamos un JscrollPane y le agregamos la JTable
     JScrollPane scrollPane = new JScrollPane(table);
     add(scrollPane);
}
