title: CKEditor removes class attribute from table
body: <p>In my <code>&lt;textarea&gt;</code>, I have this text:</p>
  
  <pre><code>&lt;table class='table table-striped'&gt;
  &lt;tr&gt;
  &lt;td&gt;1&lt;/td&gt;
  &lt;td&gt;2&lt;/td&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>After using <code>CKEDITOR.replace()</code>, my text area become a CKEditor and it has a table in it. The problem is CKEditor adds its class to my table called <code>cke_show_border</code>. Only attributes in that class are applied to the table, none of my class is applied.</p>
  
  <p>What should I do to make it apply my <code>table</code> and <code>table-striped</code> class?</p>
  
  <p>Thanks for your help.</p>
