Kommentarer

Använd egenskapen Height för att ange höjden (i bildpunkter) för cellen som representeras av en instans av HtmlTableCell klassen. När du anger höjden på en cell delar alla celler i samma rad automatiskt den höjden.

Note

Om du anger en höjd som är mindre än vad som krävs för att visa innehållet i cellen ignoreras den här egenskapen.
