[jQuery] paint columns in alternating colour

[jQuery] paint columns in alternating colour


i have this table structure - a database feeds rows into it with
Class=Row or AltRow
I want to paint the columns in alternating colours for both Row and
AltRow for readability
I tried:
$(document).ready(function(){
$(".Grid>.Row>td:even").css("background","silver");
});
and other variations - i'm having difficulty selecting the TD's in the
TR of Class 'Row' which is in the table of class 'Grid' - at one point
i got a checkerboard effect :) I can give the table an ID if that's
better to pick things out
Any help appreciated

<table class="Grid" cellspacing="0" cellpadding="0">
