Bootstrap grid with both equivalent table rowspan and colspan

Question

I am trying to create a layout like this one in bootstrap3

Found something similar here but not able to make it work:

https://jsfiddle.net/SxcqH/52/

.container {
    margin-top: 10px;
}

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>

<div class="row-fluid">
    <div class="span4"><div class="well">1<br/><br/><br/><br/><br/></div></div>
    <div class="span8">
        <div class="row-fluid">
            <div class="span6"><div class="well">2</div></div>
            <div class="span6"><div class="well">3</div></div>
        </div>
        <div class="row-fluid">
            <div class="span6"><div class="well">4</div></div>
            <div class="span6"><div class="well">5</div></div>
        </div>
    </div>
</div>
<div class="row-fluid">
    <div class="span4">
        <div class="well">6</div>
    </div>
    <div class="span4">
        <div class="well">6</div>
    </div>
    <div class="span4">
        <div class="well">6</div>
    </div>
</div>

I was able to do it with a nested grid

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" />

<div class="row">


  <div class="row mx-auto" style="height: 200px;">
    <div class="col-sm-6">

      <div class="row "> <!-- nested row 1 -->
        <div class="col-sm-12 "> <!-- nested quick links col -->
          AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
        </div>

        <div class="row"> <!-- nested row 2 -->
          <div class="col-sm-6">
            BBBBBBB
          </div>
          <div class="col-sm-6">
            CCCCCCCCC
          </div>

        </div>

      </div>
    </div>

    <div class="col-sm-3"> DDDDDD </div>

  </div>
</div>
