How to add spacing between elements of bootstrap enabled html table?

Question

This fiddle: https://jsfiddle.net/DTcHh/10952/ displays 8 table elements, but I'm unable to add spacing between each element.

I've tried :

cellpadding="3" cellspacing="3" 

as well as:

td:nth-child(2) {
    padding-right: 20px;
}

but these options do not seem to have desired effect.

<div class="center">

  <div>
    <table class="table table-bordered" cellspacing="1">
      <tr>
        <td class="col-md-3">
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>

        <td class="col-md-3" col-md-offset-2>
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>

        <td class="col-md-3">
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>




        <td class="col-md-4">
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>
      </tr>

      <tr>
        <td class="col-md-3">
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>

        <td class="col-md-3" col-md-offset-2>
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>

        <td class="col-md-3">
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>




        <td class="col-md-4">
          <div class="header"><a href="{{ module.hrefTitle }}" target="_blank">test2</div>

          <div class="title truncated-anchors"><a title="{{module.title}}" href='test");'>test</a>
          </div>

          <div class="date">test</div>
        </td>
      </tr>

    </table>
  </div>

</div>
