Following code works fine with IE, but doesn't work with other browsers.

tbl.addEventListener("keyup", OnKeyUp);
tbl.focus();
}
function OnKeyUp(event) {
alert(event.keyCode);
}
</script>
</head>
<body onload="OnLoad()">
<table id="tbl">

The problem is that the table element cannot be given focus in some browsers. If you add a tabindex property to the table, your code should work, as that will allow the table to receive focus:
<table id="tbl" tabindex="1">
<!--Rest of your code-->
</table>
Here's a working example.
