i wrote this code to make a table in wml the problem that it's not viewed correctly on 7650 and many other handsets. i know it's possible to design tables in WML but i think i'm doing something wrong. pls check the code and let me know what to do exactly to view tables correctly

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<card title="Table">
<table columns="3">
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>

thanks in advance,
