请教：用label显示内容怎么换行？

请问：用label显示内容如何换行？？
<table width="660" border="2">
  <tr>
  <td style="width:10%">
  <asp:Label ID="lb2" Text="内容:" runat="server" />
  </td>
  <td>
  <asp:Label ID="lb3" runat="server" Text="aaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbcccccccccccccccccdddddddddddddddddddddddddddeeeeeeeeeeeeeeeee" />
  </td>
  </tr>
  </table>
我想让text的内容分成多行显示，应该怎么办？？除了在字符串中加</br>
