    model.addColumn("equipo"); 
    model.addColumn("posicion");
    model.addColumn("Numero");

    model.addColumn("Liguilla");
    model.addColumn("Edad");  
    while(datostraidos.next() )
    {
      Object [] fila = new Object[7];
      for(int i=0;i<7;i++) 
      {
        fila[i]=datostraidos.getObject(i+1);
        System.out.println("for");
      }
      System.out.println("while");
      model.addRow(fila);
    }
    model.addRow(columnasname);
    gridview.setModel(model);

What does your table model looks like? Are you using a default table model?

Also, do you use a JSCrollPane? If not, adding it to a JSCrollPane works most of the times.

See this:

In this code I have two tables, one with JScrollPane, one without.

Look how the second (placed at the bottom) doesn't have headers.

By the way, this is a nice trick to provide a "results" column ;)
