Invalid attribute width inside <tr> and additionally obsolete attributes

An invalid attribute within <tr> was found. In addition, I removed several attributes which its use is discouraged in HTML5.
Update editor.php

When a bad coded or outdated (i.e.) non-compatible plugin is installed you cannot open the editor and an error is shown "Call to undefined method stdClass::onDisplay() Error". Only 2 fields are visible "Name and Alias". I posted the entire issue on https://groups.google.com/forum/#!searchin/joomla-dev-cms/$2Flibraries$2Fcms$2Feditor$2Feditor.php/joomla-dev-cms/-2EPgbbNn78/7LKB3_5Ah8IJ and will post also a Tracker item shortly. 

The code change checks to see if the class method named “onDisplay” exists before attempting to use it but will pass without throwing the error
