title: CSS Border Collapse don't work with value collapse
body: <p>I have used the css property <code>border-collapse: collapse</code>, but it seems not to be working.</p>
  
  <p>Here is the html</p>
  
  <pre><code>&lt;table cellspacing="0"&gt;
      &lt;tr&gt;
          &lt;td&gt;This is demo&lt;/td&gt;
          &lt;td&gt;This is demo&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
          &lt;td&gt;This is demo&lt;/td&gt;
          &lt;td&gt;This is demo&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
          &lt;td&gt;This is demo&lt;/td&gt;
          &lt;td&gt;This is demo&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;   
  </code></pre>
  
  <p>And the CSS</p>
  
  <pre><code>table tr td {
      border: 2px solid red;
      border-collapse:collapse;
  }
  </code></pre>
