为了得到更好的答案，您可能需要更具体。问题是理解struts2还是显示标签？ 本教程解释了如何在显示标签库中创建链接。
If struts 2 is the problem then you could make you question more specific and we'll see what we can do.
如果 struts 2 是问题，那么您可以提出更具体的问题，我们将看看我们能做些什么。

You can write your stuff within the tag like this:
你可以像这样在标签中写你的东西：
<display:table id="row" >
<display:column property="id" title="ID" paramId="id" >
<a href="details.jsp?${row.id}">Details</a>
</display:column>
</display:table>

You could also create a decorator for the table and have it generate the link. See example below on some other forum: http://sourceforge.net/forum/message.php?msg_id=4119964
您还可以为表创建一个装饰器并让它生成链接。请参阅以下其他论坛上的示例：http: //sourceforge.net/forum/message.php?msg_id= 4119964
