Can you be more specific by making a question about what is your concern?
No hay nada encima de la mesa. If you sound it out, it could either be "nada" or "nadie" but if you are talking about an object, then use "nada". If you are talking about someone not on the table, you would use "nadie" Nada: for object, Nadie: for person.
Hope this helped
