Para compatibilidad con versiones anteriores, Aspose.Cells renderiza las líneas de cuadrícula como líneas punteadas por defecto al convertir Excel a PDF. Sin embargo, Excel moderno renderiza las líneas de cuadrícula como líneas sólidas hoy.
Con la opción PdfSaveOptions.gridlineTypes, Aspose.Cells for JavaScript vía C++ también puede renderizar líneas de cuadrícula como líneas sólidas.
