Escenarios de uso posibles
Un segmentador se usa para filtrar datos rápidamente. Puede filtrar datos tanto en una tabla como en una tabla dinámica. Microsoft Excel te permite crear un segmentador seleccionando una tabla o tabla dinámica y luego haciendo clic en Insertar > Segmentador. Aspose.Cells for JavaScript vía C++ también permite crear un segmentador usando el método Worksheet.slicers.add().
Crear Cortador para una Tabla Dinámica
Por favor, vea el siguiente ejemplo de código. Carga el archivo de Excel de muestra que contiene la tabla dinámica. Luego crea el segmentador en función del primer campo base de la tabla dinámica. Finalmente, guarda el libro en formato XLSX de salida y XLSB de salida. La siguiente captura de pantalla muestra el segmentador creado por Aspose.Cells for JavaScript vía C++ en el archivo de Excel de salida.
