JQuery: How to select rows from a table

Question

I have a scenario where I would like to select rows from a table depending upon the values in td

e.g. I have a table like this

Answer 1

$("tr").each(function (index) {
   if ($.trim($(this).find('td:eq(0)').text()) == x &&
       $.trim($(this).find('td:eq(1)').text()) == y) {
       $(this).closest('table').css('border', '1px solid red');​ // this should do it
   }
}); 

Alternatively, using .filter:

$("tr").filter(function() {
    return $.trim($(this).find('td:eq(0)').text()) == 'John' &&
           $.trim($(this).find('td:eq(1)').text()) == 'Smith';
}).closest('table').find('tr').css('border', '1px solid red');​
