title: Add space and border below to row
body: <p>I have a table and I need rows with space and border below.</p>
  
  <p>Like this:</p>
  
  <p><a href="https://i.stack.imgur.com/2Ho0b.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2Ho0b.jpg" alt="enter image description here"></a></p>
  
  <p>I tried to fix it with false white borders and a 'spacer row' with black background but I do not get displayed correctly.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>table {
    border-collapse:collapse;  
  }
  td {
    padding:1em 2em;
    background-color:#ccc; 
    border-top:10px solid white;
    border-bottom:10px solid white;
    border-right:4px solid white;
    text-align:center;
    vertical-align:middle;
  }
  tr:first-child td {border-top:0}
  td:last-child {border-right:0}
  
  tr.spacer {
    height:1px;
    background-color:black;
    border:1px solid black;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;table&gt;
    &lt;tr&gt;
      &lt;td&gt;One&lt;/td&gt;
      &lt;td&gt;Two&lt;/td&gt;
      &lt;td&gt;Three&lt;/td&gt;
      &lt;td&gt;Four&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr class="spacer"&gt;&lt;/tr&gt;
    &lt;tr&gt;
      &lt;td&gt;One&lt;/td&gt;
      &lt;td&gt;Two&lt;/td&gt;
      &lt;td&gt;Three&lt;/td&gt;
      &lt;td&gt;Four&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr class="spacer"&gt;&lt;/tr&gt;
    &lt;tr&gt;
      &lt;td&gt;One&lt;/td&gt;
      &lt;td&gt;Two&lt;/td&gt;
      &lt;td&gt;Three&lt;/td&gt;
      &lt;td&gt;Four&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
    </code></pre>
  </div>
  </div>
