这段时间在做一个报表,关于<ww:iterator> 迭代?Map<String,List<AspectVo>> ?AspectVo是个对象,

具体页面如下:

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
   <th width="100%" height="30px" align="center" valign="middle" class="list_gridRB" colspan="6">二级分类统计表(本级接收)</th>
   </tr>
    <tr>
	<th rowspan="2" colspan="2" align="center" valign="middle" class="list_gridRB">内容分类</th>
	<th colspan="4" height="20" align="center" valign="middle" class="list_gridRB">网上信访量</th>
	</tr>
	<tr>
	<th height="20" align="center" valign="middle" class="list_gridRB">本期</th>
	<th height="20" align="center" valign="middle" class="list_gridRB">上期</th>
	<th height="20" align="center" valign="middle" class="list_gridRB">环比</th>
	<th height="20" align="center" valign="middle" class="list_gridRB">占比</th>
	</tr>
	<ww:iterator value="object.keySet()" id="key">
	<tr>
	<td width="20%" align="center" valign="middle" class="list_gridRB" rowspan="<ww:property value="(object.get(#key)).size()"/>"><ww:property value="#key"/></td>
	<ww:iterator value="object.get(#key)" status="status">
	<ww:if test="#status.count == 1">
	 <td width="20%" height="20"  ><ww:property value="aspectName"/></td>
	<td height="20"  ><ww:property value="base"/></td>
	<td height="20" ><ww:property value="pre"/></td>
	<td height="20"  >
	 <ww:if test="hPecent=='.00%'">0.00%</ww:if>
	<ww:else><ww:property value="hPecent"/></ww:else>
	</td>
	<td height="20" align="center" valign="middle" class="list_gridRB">
	<ww:if test="zPecent=='.00%'">0.00%</ww:if>
	 <ww:else><ww:property value="zPecent"/></ww:else>
	 </td>
	</ww:if>
	</ww:iterator>
	</tr>
	<ww:iterator value="object.get(#key)" status="sta">
	<ww:if test="#sta.count > 1">
	<tr>
	<td height="20"  ><ww:property value="aspectName"/></td>
	<td height="20"  ><ww:property value="base"/></td>
	<td height="20"  ><ww:property value="pre"/></td>
	 <td height="20"  >
	 <ww:if test="hPecent=='.00%'">0.00%</ww:if>
	 <ww:else><ww:property value="hPecent"/></ww:else>
	 </td>
	  <td height="20" align="center" valign="middle"  >
	<ww:if test="zPecent=='.00%'">0.00%</ww:if>
	 <ww:else><ww:property value="zPecent"/></ww:else>
	 </td>
	  </tr>
	 </ww:if>   
		</ww:iterator>
	</ww:iterator>
 </table>
