Créer, manipuler ou supprimer des scénarios des feuilles de calcul avec JavaScript via C++

Contents
[ ]

Aspose.Cells fournit quelques classes utiles, par exemple, ScenarioCollection, Scenario, ScenarioInputCellCollection, et ScenarioInputCell. Elle offre également la propriété Worksheet.scenarios. Le code exemple ci-dessous ouvre un fichier Excel XLSX contenant quelques scénarios et supprime un scénario existant. Il ajoute également un nouveau scénario dans la feuille avant de sauvegarder le fichier Excel. L’exemple utilise un fichier modèle très simple contenant un scénario.
