Centring Tables in HTML 4.01 Strict...?

Hi,

I've got a question that has been bothering me for a while now.  The HTML 4.01 Strict specifications have declared the "align" attribute of the 
<table> tag as deprecated.  HOW are we supposed to centre a table in the browser window? I've tried everything I can think of, with no real 
solution.  For instance, the following CSS declaration produces only partial results; the browsers that I would expect to support it, don't:

body { text-align:center }

The results:

IE 5.5: centres the table
Netscape 4.77: centres the table
Netscape 6.2: table remains left-aligned; individual cell contents are centred
Opera 6.02: table remains left-aligned

Perhaps I'm missing the obvious.  Any help would be appreciated!
