forEach

<c:forEach begin="1" end="12" step="1" var="num">
<tr>
<td height="25" align="center" valign="middle"class="list_company"><label name="year${num}" ></label></td>
</tr>

</c:forEach>

类似于java代码

for(int i = 1; i <= 12; i++){

<tr>
<td height="25" align="center" valign="middle"class="list_company"><label name="year"+i} ></label></td>
</tr>

}

<c:forEach items="${sorts}" var="sort"> 
<option value="${sort.task_sort_id}">${sort.task_sort_name}</option> 
</c:forEach> 

遍历sorts
