title: Does a table cell have a containing block?
body: <p>According to <a href="http://www.w3.org/TR/CSS2/visudet.html" rel="noreferrer">http://www.w3.org/TR/CSS2/visudet.html</a>, some elements can have a "containing block". Does a table cell <code>td</code> have a containing block, like <code>tr</code>?</p>
  
  <p>e.g. </p>
  
  <pre><code>&lt;div&gt;
      &lt;table&gt;
          &lt;tr&gt;
              &lt;td&gt;hi&lt;/td&gt;
          &lt;/tr&gt;
      &lt;/table&gt;
  &lt;/div&gt;
  </code></pre>
