Adattare automaticamente le righe per celle unite con JavaScript tramite C++
Contents

Microsoft Excel fornisce una funzione che consente di dimensionare automaticamente l’altezza di una cella in base al suo contenuto. La funzione si chiama adattamento automatico delle righe. Microsoft Excel non imposta l’operazione di adattamento automatico sulle celle unite in modo nativo. A volte la funzione diventa vitale per un utente che ha davvero bisogno di implementare l’adattamento automatico delle righe anche sulle celle unite.
Come utilizzare AutoFitMergedCellsType per l’adattamento automatico delle righe
Aspose.Cells for JavaScript tramite C++ supporta questa funzione tramite l’API AutoFitterOptions.autoFitMergedCellsType. Utilizzando questa API, è possibile adattare automaticamente le righe in un foglio di lavoro, comprese le celle unite. Ecco un elenco di tutti i tipi possibili di adattamento automatico delle celle unite:
- Nessuna
- Prima riga
- Ultima riga
- Ogni riga
Autoadattamento righe per celle unite
Vedi il seguente codice, crea un oggetto workbook e aggiunge più fogli di lavoro. Utilizza metodi diversi per le operazioni di autofit in ogni foglio di lavoro. Lo screenshot mostra i risultati dopo l’esecuzione del codice di esempio.
