回答1:

You can write your stuff within the tag like this:

<display:table id="row" >
    <display:column property="id" title="ID" paramId="id"  > 
        <a href="details.jsp?${row.id}">Details</a>
    </display:column>
</display:table>

回答2:

It is done by the following code.

<display:column  title="Edit">
                    <s:url id="updateUrl" action="marketing/update.action">
                        <s:param name="id" value="#attr.countrylist.id" />
                    </s:url>
                    <s:a href="%{updateUrl}" theme="ajax"  targets="countrylist">Update</s:a>
                </display:column>

Thanks for all the answers

You may have to be more specific in order to get better answers. Is the problem understanding struts2 or display tags? This tutorial expains how to create links in display tags library.

If struts 2 is the problem then you could make you question more specific and we'll see what we can do.

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
