Aspose.Cells - Aggiungi commenti nel foglio di calcolo
Aggiungi un commento a una cella chiamando il metodo addComments della collezione Shapes (incapsulato nell’oggetto Worksheet). Il nuovo oggetto Comment può essere accesso dalla collezione Comments passando l’indice del commento. Dopo aver accesso all’oggetto Comment, personalizza la nota del commento utilizzando il metodo setNote dell’oggetto Comment.
Java
//Instantiating a Workbook object
Workbook workbook = new Workbook();
//Adding a new worksheet to the Workbook object
Worksheet worksheet = workbook.getWorksheets().get(0);
//Adding a comment to cell
int commentIndex = worksheet.getComments().add("A1");
Comment comment = worksheet.getComments().get(commentIndex);
//Setting the comment note
comment.setNote("Hello Aspose!");
