title: overflow:scroll; in <td>
body: <p>Why does the CSS property <code>overflow:scroll;</code> not work in <code>&lt;td&gt;</code>, while <code>overflow:hidden;</code> works well?</p>
  
  <pre><code>&lt;table border="1" style="table-layout:fixed; width:100px"&gt;
    &lt;tr&gt;
      &lt;td style="overflow:scroll; width:50px;"&gt;10000000000000000000000000000000000&lt;/td&gt;
      &lt;td&gt;200&lt;/td&gt;
      &lt;td&gt;300&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>From the CSS specs<sup><a href="http://www.w3.org/TR/CSS2/visufx.html#overflow" rel="noreferrer">1</a>,<a href="http://www.w3.org/TR/CSS2/tables.html#fixed-table-layout" rel="noreferrer">2</a></sup>, I can't see why.</p>
