docs: Sets liner DIV elements of given Column to given width. When value should be
  auto-calculated to fit content overflow is set to visible, otherwise overflow
  is set to hidden. No validations against minimum width and no updating
  Column.width value.
  
  @method _setColumnWidth
  @param oColumn {YAHOO.widget.Column} Column instance.
  @param sWidth {String} New width value.
  @param sOverflow {String} Should be "hidden" when Column width is explicitly
  being set to a value, but should be "visible" when Column is meant to auto-fit content.
