Commenti

Utilizzare la Width proprietà per specificare la larghezza (in pixel) della cella rappresentata da un'istanza della HtmlTableCell classe. Quando si specifica la larghezza per una cella, tutte le celle nella stessa colonna condividono automaticamente tale larghezza.

Nota

Se si specifica una larghezza inferiore a quella necessaria per visualizzare il contenuto della cella, questa proprietà viene ignorata.
