/**
 * @class Roo.htmleditor.FilterTableWidth
  try and remove table width data - as that frequently messes up other stuff.
 * 
 *      was cleanTableWidths.
 *
 * Quite often pasting from word etc.. results in tables with column and widths.
 * This does not work well on fluid HTML layouts - like emails. - so this code should hunt an destroy them..
 *
 * @constructor
 * Run a new Table Filter
 * @param {Object} config Configuration options
