我要在 <td>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("AccountCd").ToString() + ": " + Eval("Descr").ToString()%>'></asp:Label>
</td>输出那个效果 --------------------编程问答-------------------- Label 是没有表格效果的，
思路都给你了，用什么控件不是改一下就行了吗？我不明白使用Label 你要显示什么效果？ --------------------编程问答-------------------- 如我不想用repeater控件嵌套实现，应该怎么办呢 --------------------编程问答-------------------- 怎么办？有很多种方法啊，你可以循环拼接字符串显示，
你为什么不想进行嵌套？ --------------------编程问答-------------------- 用嵌套好，而且用得样式定义起来灵活 --------------------编程问答-------------------- 应为我是在别人做好的页面上实现那个功能 --------------------编程问答-------------------- 嵌套吧 听话。。。 --------------------编程问答-------------------- 可以用中间表在数据库中处理，不需要在页面上面处理，希望对你有帮助 --------------------编程问答-------------------- 那用嵌套的话怎么改，能帮我改改吗？
