Why not? You can always use an <a> tag to call a JavaScript function.
Here's the most common way:
<display:table name="contacts" id="contactList">
<display:column>
<a href="/path" onclick="document.forms[0].submit(); return
false"><c:out value="${contactList.name}"/></a>
</display:column>
</display:table>
