Twitter bootstrap 3 跨越2行的引导列

我试图让一个引导列跨越2行。我一直在看，但在我的项目背景下，它似乎不起作用

有人能告诉我要使右边的列跨越两行需要做什么吗

<div class="container" style="background-color: #fff">
    <div class="row" style="background-color: #fff">
    <div class="col-md-4">
        <img src="public/img/index/Hola_Sevila.png" style="width:180px">
      <h6>Hola Sevilla!</h6>
      <p>I recently had the pleaseure and the privilege of travelling to the ...</p>
        <p><a href="#">Read More</a></p>
    </div>
    <div class="col-md-4">
        <img src="public/img/index/Trans_helps_children.jpg" style="width:180px">
        <h6>Translation helps children</h6>
      <p>De La Salle Solidarieta Internatazionale ONLUS is a non-profit organisation that fundraises ...</p>
        <p><a href="#">Read More</a></p>
   </div>
    <div class="col-md-4 two_row_column">
        <div class="index-b-right-1"></div>
        <div class="index-b-right-1">
            <h3>Videos</h3>
        </div>
        <div class="index-b-right-1">
            <h3>Be a Friend</h3>
        </div>
        <div class="index-b-right-2">
            <h4>You can show your appreciation and support future development              by becoming a friend of the Rosetta</h4>
        </div>
        <div class="index-b-right-3">
            <h3><a href="#">Donate</a></h3>
        </div>
        <div class="index-b-right-1"></div>

    </div>
  </div>

我猜这就是你想做的？ 我解释它的简单方法是，创建最上面的行，在该行中创建列，然后在另一列中创建另一行，然后将其划分为各个列

希望有帮助
