Horarios

Datos con marca de tiempo en formato tabular

Un timetable (horario) es un tipo de tabla que asocia una hora con cada fila. Al igual que una table (tabla), el tipo de dato timetable puede almacenar variables de datos orientadas a columnas que tienen la misma cantidad de filas. Todas las funciones de la tabla funcionan con horarios. Además, los horarios proporcionan funciones específicas de tiempo para alinear, combinar y realizar cálculos con uno o más horarios. Para obtener más información, consulte Create Timetables o vea Gestión de datos tabulares con marca de tiempo con horarios.
