$("#showComp tr:not('.stlisttitle')").hover(function(){
        try{if($("#calendarPanel").is(":visible")) $(".playerlist").hide();else{clearTimeout(timMess);
        $(".playerlist").css("top",$(this).offset().top-$(".calendarCon").offset().top-30).show();}}catch(e){}

    },function(){
        timMess=setTimeout(function(){
            $(".playerlist").hide();
         },300);

        //$(this).css("background","");
    });    
    $(".playerlist").hover(function(){
        clearTimeout(timMess);
    },function(){
        timMess=setTimeout(function(){
            $(".playerlist").hide();
         },300);
    });

The effect is as follows:
