struts多列列表显示

结合struts的iterate tag+JSTL1.1实现多列列表的显示。下面一段示例代码中显示的是2列，如果想显示多列，则直接把2改成自己想显示的列数即可。

<nested:iterate property="items" indexId="index">
                                                  <c:if test="${index%2==0}">
                                                  <tr>
                                                  </c:if>   
                                                     <td>
                                                        ${index}
                                                     </td> 
                                                  <c:if test="${(index+1)%2==0}">
                                                     </tr>
                                                </c:if>
11                                            
12                                         </nested:iterate>
