Créer l’union de la plage
Aspose.Cells offre la possibilité de créer une plage d’union en utilisant la méthode WorksheetCollection.createUnionRange. La méthode WorksheetCollection.createUnionRange accepte deux paramètres, l’adresse pour créer la plage d’union et l’indice de la feuille de calcul. La méthode retourne un objet UnionRange.
Le code suivant démontre la création d’une plage d’union en utilisant la méthode WorksheetCollection.createUnionRange. Le fichier de sortie généré par le code est joint pour référence.
