c:forEach实现换行

Map<String,String> map = new TreeMap<String,String>();
map.put("key1", "value1");
map.put("key2", "value2");
map.put("key3", "value3");
map.put("key4", "value4");
map.put("key5", "value5");
map.put("key6", "value6");
map.put("key7", "value7");
request.setAttribute("map", map);  

<tr>
    <c:forEach items="${map}" var="note" varStatus="status">
        <c:if test="${status.index%2==0}">
            </tr>
            <tr>
        </c:if>
        <td>${note.key }</td>
        <td>${note.value }</td>
    </c:forEach>
</tr>
