Ideas on how to improve table plugin

Question

Took me a while(attempts) to get this working exactly how I want but I thought I would post it here for suggestions to improvements(performance/accessibility).

$('table').each(function(){
    var $table= $(this), $cell, $row;
    /*
     * Badass Table Row
     * 1. Click row redirect to url
     *    @param tr[data-url]
     * 2. Double click row load link. First checks last cell or any link
     * 3. Cells with checkboxes, phpmyadmin style click cell toggles child checkbox     
     */ 
    $table.find('tr').each(function(){
        $row = $(this);

        var url = $row.attr("data-url");
        if(url && url.length){
            $row.addClass("table-row-click").find("td").click(function(){
                window.location = url;
                return false;
            });    
        }  

        $row.children('td').each(function(){
            $cell = $(this);

            if($cell.find("input[type=checkbox]").length){
                $cell.addClass("table-cell-hasCheckbox").click(function(e) {
                    if(e.target.type !== 'checkbox') $(':checkbox', this).trigger('click');
                });
            }

            // Double click open edit link
            if(!$table.hasClass("table-noDoubleClick")){
                $cell.dblclick(function(e){
                    var linkEl = $(this).parents('tr').find('td:last-child a');
                    if(!linkEl.length) linkEl = $(this).parents('tr').find('td a');
                    var linkElHref = linkEl.attr('href');

                    // Check if has href and http protocol
                    if(linkElHref && (!linkElHref.length || linkEl.prop('protocol').indexOf("http") !== 0)){
                        e.preventDefault();
                        return false;
                    }

                    if (linkElHref && linkEl.attr('onclick') === undefined && !linkEl.hasClass("popup")) {
                        document.location = linkElHref;
                    } else {
                        linkEl.click();
                    }
                });
            }          
        }); // end CELLS                 
    }); // end ROWS
}); // end TABLE
