$("tr:last") not working

[josephantoney]

first of all i want to thank JQuery dev team & supporters.

The problem that i faced:

1. $("tr:last").css("font-style", "italic"); doesn't works against table(s) i have

2. I have two simple tables if i use

$("tr:even").css("font-style", "italic"); i can see the changes on both tables

but if i use

$("tr:first").css("font-style", "italic"); style applies on only 1st table and not on the second

Am using firefox 3.5.3
