I am unable to form table in List<String> using struts 2 tags
public class IteratorAction extends ActionSupport{

    private List<String> list;

    public List<String> getList() {
        return list;
    }

    public void setlist(List<String> list) {
        this.list= list;
    }

    public String execute() {

        list= new ArrayList<String>();
        list.add("A");
        list.add("B");
        list.add("C");
        list.add("D");
        list.add("E");
        list.add("F");

        return SUCCESS;
    }
}

<table>
<s:iterator value="list" status="listStatus">
  <tr>
    <s:if test="#listStatus.even == true">
      <td style="background: #CCCCCC"><s:property/></td>
    </s:if>
    <s:elseif test="#listStatus.first == true">
      <td><s:property/> (This is first value) </td>
    </s:elseif>
    <s:else>
      <td><s:property/></td>
    </s:else>
  </tr>
</s:iterator>
</table>
