You can use GAP to export the values from the character table library into a CSV file (openable with notepad or excel).

gap> ct:= CharacterTable("M");;
gap> classes := List( [ "1a", "2a", "2b" ],
> name -> Position( ClassNames( ct ), name ) );;
gap> PrintTo( "mon.csv", "1A,2A,2B\n", JoinStringsWithSeparator( List( Irr(ct),
> chi -> JoinStringsWithSeparator( chi{classes}, "," ) ), "\n" ) );

Here is the result.
