style tag not working in Netscape 4.X

[Ravi upasi]

HI,
I am designing a web page. which has mainly a table.
I want the table to fit to window.
SO i have used the Style tag as below in my Html code.
<STYLE type="text/css">
<!--
body { margin:0px;}
table { margin:0px;}
-->
</STYLE>
So itas working fine in IE.5 as well as IE.6
But the style tag does'nt have any effect in Netscape 4.x
so can any one provide a solution for making it work in Netscape 4.x also
thanks in advance.
