Medir el ancho y alto del valor de la celda en unidades de píxeles

A veces necesitas calcular el ancho y la altura del valor de la celda para que encaje dentro de la celda. Aspose.Cells proporciona métodos Cell.widthOfValue y Cell.heightOfValue para este propósito. Usando estos métodos puedes calcular el ancho y la altura del valor de la celda y luego establecer el ancho de la columna y la altura de la fila de esa celda respectivamente y así ajustar o encajar el valor de la celda dentro de la celda
alternativamente, también puedes autoajustar filas y columnas de tu celda o rango de celdas usando las APIs de Aspose.Cells.
El siguiente código explica el uso de los métodos Cell.widthOfValue y Cell.heightOfValue.
