[jQuery] children() passable variables there

[jQuery] children() passable variables there

Hello.
I am trying to do
        $("tbody tr").each(function(){
            $(this).children("td:first").css({
                'border-left': '3px solid #EEEEEE',
            });
            $(this).children("td:last").css({
                'border-right': '3px solid #eeeeee',
            });
            $(this).children("td:not(:first:last)").css("text-align", "center");
        });
This works in Firefox 3.5 but somehow it bogs down in IE7+
I also tried with td:eq(0) and td:eq(4) (have 5 columns)
help?
