So, you want to update the name of input with name id0 in second last row?

$('#myTable tr:last-child').prev().find(' td input[name="id0"]').attr('name', 'id1');

http://api.jquery.com/eq-selector/

Unlike the .eq(index) method, the :eq(index) selector does not accept a negative value for index. For example, while $('li').eq(-1) selects the last li element, $('li:eq(-1)') selects nothing.

Try this :
$('#myTable tr').eq(-2).find('input[name="id0"]').attr('name', 'id1');
