Propongo esta simplificación del código con makecell. Los números están (parcialmente) alineados con el Stipo de columna de siunitxy la tabla puede caber en la página, utilizando el sidewaystableentorno. Eliminé todas las líneas verticales, reemplazando algunas de ellas con un espacio entre grupos de columnas. Por último, utilicé las reglas horizontales de booktabs.
