It does not need to be (but often is, in particular if the table is computed from scratch for a given group the classes are just taken as given by the group). If the table was taken from a library of existing tables, for example by connecting a given table with a given group, however, it is possible that the arrangement will differ. Because of this, the attribute IdentificationOfClasses for a character table holds the corresponding class numbers of the underlying group. See the manual chapter The Interface between Character Tables and Groups http://www.gap-system.org/Manuals/doc/htm/ref/CHAP069.htm#SECT006 for more details.
