Aggiungi commenti nel foglio di calcolo in xlsx4j

Aspose.Cells - Aggiungi commenti nel foglio di calcolo

Aggiungi un commento a una cella chiamando il metodo addComments della raccolta Shapes (incapsulato nell’oggetto Worksheet). È possibile accedere al nuovo oggetto Comment dalla raccolta Comments passando l’indice dei commenti. Dopo aver effettuato l’accesso all’oggetto Comment, personalizzare la nota di 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!");
