I made a little modification on your HTML code by changing the names of the checkboxes in the table body from cbn to cb[] (better for server operations). I also took in account the fact that the main checkbox state can be changed by clicking on another checkbox: if the user manually selects all the other checkboxes, then the main checkbox should reflect it; also, if the user unchecks a row after clicking the main checkbox to check all the others, then the main checkbox should get unchecked.

You can see it working there : https://jsfiddle.net/h6tgj02p/

<tableborder="1"><thead><tr><th><inputtype="checkbox"id="allcb"name="allcb"/></th><th>values</th></tr></thead><tbody><tr><td><inputtype="checkbox"id="cb1"name="cb[]"/></td><td>value1</td></tr><tr><td><inputtype="checkbox"id="cb2"name="cb[]"/></td><td>value2</td></tr><tr><td><inputtype="checkbox"id="cb3"name="cb[]"/></td><td>value3</td></tr></tbody></table><scripttype="text/javascript">
$(document).ready(function() {

    /*
    * Click on select all checkbox
    */
    $('#allcb').click(function(e) {
        $('[name="cb[]"]').prop('checked', this.checked);
    });

    /*
    * Click on another checkbox can affect the select all checkbox
    */
    $('[name="cb[]"]').click(function(e) {
        if ($('[name="cb[]"]:checked').length == $('[name="cb[]"]').length || !this.checked)
            $('#allcb').prop('checked', this.checked);
    });

});

</script>
