You can use is() which returns a boolean:

if (!$('table :radio').is(':checked')) {
        alert('No Radio Button Selected');
    }

If at least one radio button is checked, this won't fired alert()

DEMO

In the code you can replace table with #tableID so that code only runs for that table

$(document).ready(function () {
    if ($('table input[type=radio]:checked').length < 1) {
        alert('No Radio Button Selected');
    }
});

if you want to notify on table click

 $('table').click(function () {
        if ($('table input[type=radio]:checked').length < 1) {
            alert('No Radio Button Selected');
        }
    });

$('#table input:radio:checked') will give the radios checked inside table with id `#table`
