title: Can Sass select element by postion?
body: <p>There is a table, and there is no <code>id</code> with <code>td</code></p>
  
  <pre><code>&lt;table id='mytable'&gt;
     &lt;tr&gt;
       &lt;td&gt;
           I want to right without id 
       &lt;/td&gt;
  
       &lt;td&gt;
           I want to left without id
       &lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>How to make the content of the first <code>td</code> align right and the second align left ? </p>
