I don't think ajax will work cross domain, so you'll need to call a script on your own website to get the data, or you might be able to use an iframe, but I think then you can't manipulate it's contents if it's on another domain as well...
To answer the question of reading data from the url and placing it in a table you could do something like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=windows-1250">
<meta name="generator" content="PSPad editor, www.pspad.com">
<title></title>
<script type="text/javascript">
function createTable() {
var params = document.location.search.substr(1).split('&');
var table = document.createElement('table');
var tbody = document.createElement('tbody');
table.appendChild(tbody);
for(var i=0;i<params.length;i++) {
var pair = params[i].split('=');
var tr1 = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
td1.innerHTML = pair[0];
td2.innerHTML = pair[1];
tr1.appendChild(td1);
tr1.appendChild(td2);
tbody.appendChild(tr1);
}
document.getElementById('container').appendChild(table)
}
</script>
</head>
<body>
<div id="container"></div>
<script type="text/javascript">
// this script strips everything after ? and puts the fields in the first td and the value in the second td
//
createTable();
</script>
</body>
</html>
