Cómo gestionar tu error lo describo en mi comentario. Aquí me gusta mostrar cómo escribiría tu tabla:

ingrese la descripción de la imagen aquí

  • agregue el paquete siunitxpara configurar la columna de la tercera tabla de forma más agradable y sencilla
  • agregue booktabspaquetes para reglas horizontales (usted está en el sitio opuesto de personas, donde todas las filas están separadas por \hline, no tiene nadie :-))
