Table Plugin: select row/col in IE7, IE8 does not show Table Row/Col panel

Selecting row/col throw a javascript exception (﻿range [WrappedRange(<DIV>[1]:0, <DIV>[1]:1)] did not consist of a single element) which causes that the  Table Row/Col Panel is not displayed. The problem resides in the rangy-core and how it deals with selection for IE7 and IE8. The selection for this versions behaves different than for earlier version (IE9+).
