How to clean the html output of textfield using CKeditor? I have a textfield using the wysiwyg http://drupal.org/project/ckeditor text editor module. 

If I insert a table in the text then the table is wrapped with the following tags

&lt;p&gt;
    &amp;nbsp;&lt;/p&gt;


I thought that the http://drupal.org/project/htmlpurifier module would remove this tags but it doesn't. 

How can I remove these lines?
I have run into this, I'm not sure if there is a configuration value to avoid this. I usually end up installing Empty Paragraph Killer.


  Empty paragraph killer is a filter module, helpful on sites which use
  WYSIWYG editors.
  
  People often hit the return key twice at the end of a paragraph. Most,
  if not all site layouts manage the paragraph spacing, so the extra
  empty paragraphs created can detract from the look and feel of a site.
  This module filters out the empty paragraphs of all user-entered data
  on a site. It does so by following the fundamental Drupal way -
  non-destructively.
