備註
VAlign使用 屬性可指定類別實例 HtmlTableCell 所代表儲存格中內容的垂直對齊方式。
注意
設定此屬性只會影響類別實例所代表的 HtmlTableCell 儲存格。 若要將相同的垂直對齊套用至資料表中整個資料列的儲存格，請設定 VAlign 類別實例所代表之資料列的 HtmlTableRow 屬性。
下表列出可用於此屬性的值。
| 值 | 描述 |
|---|---|
Top |
將儲存格的內容對齊儲存格的上邊緣。 |
Middle |
對齊儲存格中央的儲存格內容。 |
Bottom |
對齊儲存格的下邊緣儲存格內容。 |
注意
您也可以使用 BaseLine 做為這個屬性的值。 不過，並非所有瀏覽器都支援此功能。
