title: Why does overflow:hidden not work in a <td>?
body: <p>I've got a table cell that I would always like to be a particular width. However, it doesn't work with large strings of unspaced text. Here's a test case:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>td {
    border: solid green 1px;
    width: 200px;
    overflow: hidden;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;table&gt;
    &lt;tbody&gt;
      &lt;tr&gt;
        &lt;td&gt;
          This_is_a_terrible_example_of_thinking_outside_the_box.
        &lt;/td&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>How do I get the text to be cut off at the edge of the box, rather than having the box expand?</p>
