jQuery: How to count table columns?

Answer 1

To circumvent the td/th issue (and also fix a potential issue where attr('colspan') was giving me strings) I went with this:

var colspan = 0;
$('#table').find('tr:first').children().each(function(){
    var cs = $(this).attr('colspan');
    if(cs > 0){ colspan += Number(cs); }
    else{ colspan++; }
});
