#exceptions is a html table. I try to run the code below, but it doesn't remove the table row. 
$('#exceptions').find('tr').each(function(){
    var flag=false;
    var val = 'excalibur';
    $(this).find('td').each(function(){
        if($(this).text().toLowerCase() == val) 
            flag = true;
    });
    if(flag)
        $(this).parent().remove($(this));
});
What is the correct way to do it?
