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>
