how to filter column in gridview using jquery

Hi All,
in my application i want to check the column in gridview and also avoid first column in every row.
i tried this code
$("#GridView1 td").filter(":not(td:firstt)").each(function () {

var cellText = $(this).text();
if ($.trim(cellText) == '') {
$(this).css('background-color', 'LightGreen');
$(this).text('available');
}
else {
$(this).css('background-color', 'LightBlue');
}

});
this code works only for first cell.
my requirement is avoid first cell of every row.
how to solve this code

Regards
Baiju
