Tabulators in CSS2 ?

Hi,
I wonder whether there are tabulators in CSS current spec
or it is planned for the future spec versions ?
Under tabs I mean some entity that has a set of numbers
(like a rule) and can be adjusted with respect to user needs.
E.g.:
     TAB { tab-example: 1cm 2.5cm 5cm 10cm }
Thus data delimited by corresponding tag (namely <TAB/>)
will be located at specified positions:
a<TAB/>b<TAB/>c<TAB/> will result in:
a    b          c    ....

Any notice is welcome,
