Outline numbering

I know that outline numbering can be achieved in some browsers using
css counters (http://tinyurl.com/2pe9ha), but these aren't supported
by IE. Is the only way of doing outline numbering that works in IE to
use two-column borderless tables and manually-typed numbering, or is
there a better way?

As in:

1. hkhkl
1.1 kuhkjhk
1.2 hkjhkh
2. hkjhkhl
2.1 kjhkjhk
2.1.1 hkuhkj

etc.
