HTML

<html>
<body>
    <table id="plugin">
        <tr>
            <td>
                <object width="300" height="200" data="data:application/x-silverlight," type="application/x-silverlight">

            </td>

</body>
</html>

CSS

#plugin {
    border: 5px solid black;
    margin: 10px;
    padding: 2px;
}

JavaScript

var rMargin = $('#plugin').css('margin-right');
$('#rMargin').text(rMargin);


// Possible fix
jQuery.cssHooks.marginRight = {get: function (elem, computed) {
    var ret;
    if(elem.nodeName.toLowerCase() === "table") {
        ret = elem.style.marginRight;
    } else {
        jQuery.swap( elem, { "display": "inline-block" }, function() {
            if ( computed ) {
                ret = curCSS( elem, "margin-right", "marginRight" );
            } else {
                ret = elem.style.marginRight;
            }
        });
    }
    return ret;
}};
