Commenti

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

Nota

Se si specifica un'altezza minore di quella necessaria per visualizzare il contenuto della cella, questa proprietà viene ignorata.
