detect the widest cell w/ jQuery

Question

I have a table with different values. First column contains labels. I need to get the width of the widest label. I assume I need some sort of a loop, but then what?

Answer 1

var w = 0;
$("#myTable tr td:first").each(function(){
    if($(this).width() > w){
        w = $(this).width();
    }
});
