I've been using
<table align="center"> in my pages for a few months now because I couldn't get my tables to center align with
style="margin: 0px auto". Until today, I found this tip with a simple search on Google.
As demonstrated in this simple example
page, IE5/Mac centers tables using the correct margin styles if they
are written in long-form as
margin-right:auto;. The shorthand forms such as
auto; do not work. Fortunately this bug is easily worked around by
using the long-form syntax.
Good to know, life just got a little easier.
