title: Overflow attribute on <td> does not create a scrollbar
body: <p>I trying to create a table cell <code>&lt;td&gt;</code> with an overflow but it doesn't work...</p>
  
  <p>There's my CSS code:</p>
  
  <pre class="lang-css prettyprint-override"><code>td.blog_content
  {
      max-height: 50px;
      overflow: auto;
      width: 360px;
      text-align: left;
      padding: 2px;
  }
  </code></pre>
  
  <p>And my HTML:</p>
  
  <pre class="lang-php prettyprint-override"><code>&lt;td class="blog_content"&gt;&lt;?php echo $blog['content']; ?&gt;&lt;/td&gt;
  </code></pre>
  
  <p>It would create a simple box with a scrollbar if the text is too long...</p>
