我正在使用ASP.net创建我的第一个网站，并且在格式化表格时遇到了一些问题。我希望能够让用户填写调查问卷。这是一个多部分的调查问卷，因此我使用手风琴来节省空间。第一个窗格中的一个问题有五个部分的答案。我的桌子给了我一些意想不到的行为。大约一半我尝试在五个文本框上方显示五个标签。我将它们插入表中的正确位置，但由于某种原因它们出现在页面的底部。我无法确定发生了什么。有任何想法吗？提前谢谢。

答案 0 :(得分：3)
你需要解决这个问题：
<tr>
<asp:Label ID="lblQid2_1" runat="server"></asp:Label>
<asp:Label ID="lblQ2_1" runat="server"></asp:Label>
</tr>
对于每行，您都有<tr>个标记：
<tr>
<td>
<asp:Label ID="lblQid2_1" runat="server"></asp:Label>
<asp:Label ID="lblQ2_1" runat="server"></asp:Label>
<td>
</tr>
或者这取决于您需要的每行（<td>）列数（<tr>）：
<tr>
<td>
<asp:Label ID="lblQid2_1" runat="server"></asp:Label>
</td>
<td>
<asp:Label ID="lblQ2_1" runat="server"></asp:Label>
<td>
</tr>
希望它有所帮助！
答案 1 :(得分：2)
你的html表格有<tr> table rows but no <td> table columns这可能是你的标签和文本框在页面底部移动的原因
