How to disable one check box if other is checked? JQuery/Javascript

I have the form with 4 rows and each row has 10 cells. Each cell has 2 check boxes. If one check box is checked i would like do disable the other check box and other way around. Here is example of what I have:

table.myTbl {
        width: 100%;
}
table.myTbl td {
        text-align: center;
        padding: 1px;
        margin: 0px;
        background-color: #ccc;
}

<table class="mtTbl">

I was thinking about radio buttons but there is a problem. Radio button can't be unchecked. If anyone can provide any advise or solution for this problem please let me know. Thanks in advance.
