Table控件允許您生成 HTML 表并以直接方式指定其屬性。可以用給定的靜態(tài)內(nèi)容在設(shè)計時生成表，但 Table Web 服務(wù)器控件的威力通常在用動態(tài)內(nèi)容以編程方式生成表時才會體現(xiàn)出來。 值得注意的是，以編程方式對表行或單元格所做的任何添加或修改不在向服務(wù)器的發(fā)送間保持。這是因為表行和單元格本身就是控件，而不是Table 控件的屬性。要保持對表所做的任何更改，必須在每次回送后重新構(gòu)造行和單元格。實際上，如果需要進行實質(zhì)性的修改，建議使用 DataList、DataGrid 或 GridView 控件，而不是Table 控件。因此，該Table 類主要由控件開發(fā)人員使用。
將在每個單元格中顯示靜態(tài)文本和 Hyperlink 控件。Hyperlink 控件定位到一個模擬的 URL，傳遞一個模擬產(chǎn)品 ID。由于該示例混合了靜態(tài)文本和控件，因此靜態(tài)文本Literal 對象的形式實現(xiàn)，像Hyperlink 控件一樣添加到單元格的Controls 集合中。
