    });

Answer 1

chek is a boolean value. It will never be equal to 2 (false is equivalent to 0 and true to 1), so case 2: will never be reached.

If you want to get the value of the checkbox, you have to call val():

$(".che").change(function(){
    var chek= $(this).val();
    alert(chek);
    switch(chek){
        case "1":
            alert ('ok');
            $('.myTableRow').show();
        break;
        case "2":
            alert('hora');
            $(".myTableRow").hide();
        break;
    }
});

But this setup does not seem to be logical. What should happen if both boxes are selected? It will always execute the action of the last selected checkbox.

Maybe you just want:

$(".che").change(function(){
    $('.myTableRow').toggle(this.checked); // or !this.checked
});

Although this is not really better.

You have to think about how your form should work before you implement any logic.
