两层List遍历

  1. <%
  2. 			List list = new ArrayList();
  3. 		    List list1 = new ArrayList();
  4. 		    List list2 = new ArrayList();
  5. 		    list1.add("1-a");
  6. 		    list1.add("1-b");
  7. 		    list2.add("2-d");
  8. 		    list2.add("2-c");
  9. 		    list.add(list1);
  10. 		    list.add(list2);
  11. 		    request.setAttribute("list1", list1);
  12. 		    request.setAttribute("list", list);
  13. 		%>
  14. 		<c:forEach items="${list }" var="item">
  15. 			<c:forEach items="${item }" var="item2">
  16. 				<tr>
  17. 					<td>${item2 }</td>
  18. 				</tr>
  19. 		</c:forEach>
