$("#YourbuttonId").click(function(){
    if($('#YourTableId').find('input[type=checkbox]:checked').length == 0)
    {
        alert('Please select atleast one checkbox');
    }
});

Update:

i saw your code and seems like you are using jquery validation plugin in that case this post will help you

and try giving your checkbox same name which exist in a group

See this demo: http://jsfiddle.net/RGUTv/ OR your specific case demo here: http://jsfiddle.net/J98Ua/

My old response here: validation for at least one checkbox

hope rest fits the needs! :)

code

$(document).ready(function() {
    $('#my-form').submit(function() {
        amIChecked = false;
        $('input[type="checkbox"]').each(function() {
            if (this.checked) {
                amIChecked = true;
            }
        });
        if (amIChecked) {
            alert('atleast one box is checked');
        }
        else {
            alert('please check one checkbox!');
        }
        return false;
    });
});​

try this 

$('form').submit(function(e) {
    if($("input:checked").length == 0){
    alert('please checked atleast one');
    }
});​

I'd wrap them all in a container with a div just for easier selecting, and then you can use:

if($('#wrapperID input:checked').length > 0) {
    'at least one is checked
}
