Caveats:  I'm still pretty raw at Catalyst, so I may have this  
totally wrong...and I may not completely get what you're looking for.

Would this do what you want? (untested):

     package App::C::<WHATEVER>;

     sub table_dispatcher : Regex('^admin/crud/([\w/]*)') {
         my ($self, $c) = @_;

         #  This could all be done in the Regex above, but this seems  
cleaner
         #
         my ($table, $command, $id) = split /\//, $c->req->snippets[0];

         $table = 'list_tables' unless $table;
         $c->forward($table, [$command, $id]);
    }

     sub users : Private {
         #  Deal with the 'users' table

         my ($self, $c, $args) = @_;
         my ($command, $id) = @$args;
     }


Two things I assumed that may be wrong:  I think $args comes in as an  
array ref, not as array elements in @_.  Also, I think $c->req- 
 >snippets is an arrayref (as opposed to hashref, scalar, etc).   
Also, I assumed you would want separate functions to handle each  
table.  If they all get treated the same, then you don't need the  
redispatch.
