jQuery Disable checkbox with same value

Question

So this has to be the easiest question of the day. I have below HTML structure where all input checkbox values must be unique.

    <tr>
        <td>
        <input type="checkbox" value="14292" name="chec_emp[]" class="chec_emp">
        </td>
        <td>Test User One</td>
        <td>Autobot</td>
        <td>Shadow</td>
        <td>50</td>
    </tr>

 <tr>
        <td>
        <input type="checkbox" value="14293" name="chec_emp[]" class="chec_emp">
        </td>
        <td>Test User One</td>
        <td>Autobot</td>
        <td>Billed</td>
        <td>50</td>
    </tr>


    <tr>
        <td>
        <input type="checkbox" value="14292" name="chec_emp[]" class="chec_emp">
        </td>
        <td>Test User Two</td>
        <td>Autobot</td>
        <td>Billed</td>
        <td>50</td>
    </tr>

The value 14292 is generated twice here.

If you want to add the disabled attribute to the next occurrences of checkboxes with the same value :

$('.chec_emp').each(function(){
    if ($(this).is(':enabled')) {
        $('.chec_emp[value="'+$(this).val()+'"]').not(this).prop('disabled', 'disabled');
    }
});

Brewal: The code works if the duplicate value is occuring next. But what if there is another checkbox between two checkboxes with same value ?

You can try it, but it should work. At each iteration, it looks for all other checkboxes with the same value. ("Other" beeing .not(this))

@Slimshadddyyy I updated the demo with your new html

Brewal: When I do select all to select all checkboxes, the disabled checkbox also displays selected Also one can change the disabled property from console and can again select it
