css - Bootstrap 3 网格 : column under column inside one row

Question

我有以下 HTML 代码:

<div class="row">
<div class="col-lg-3">
 <div class="panel panel-default">
  <div class="panel-body">
    Panel 1 (left)
    </div>
  </div>
</div> 

<div class="col-lg-6">
 <div class="panel panel-default">
  <div class="panel-body">
    Panel 2 (center)
    </div>
   </div>
 </div>
</div>

<div class="col-lg-3">
 <div class="panel panel-default">
  <div class="panel-body">
    Panel 3 (right)
    </div>
   </div>
 </div>
</div>

</div>

<div class="row">
<div class="col-lg-3">
 <div class="panel panel-default">
  <div class="panel-body">
    Panel 2-2 (under panel 2)
    </div>
  </div>
</div>
</div> 

最终结果应该是这样的:
它有效，但如果面板 3 的高度大于面板 1 或 2，我会得到这个:

我该如何解决？

您应该这样做，将面板 2-2 嵌套在面板 2 下，而不是让它位于末尾，这不是您想要的。这是 Bootply:http://bootply.com/102721
