Answer 1

Maybe like this? FIDDLE

I just added another condition in your if-clause.

Before:

if (index < $('#Positions_names tr').length - 1 && valid) {

After:

if (index < $('#Positions_names tr').length && valid && index >= 1) {

Alternatively:

if (index >= 1 && valid) {

Answer 2

$('tbody tr').each(function(){
        $(this).find('td:eq(5)').text('$145');
});

In above example you can skip header row by putting it into thead. I have given code to loop through the Table Body

Some Refrences, may Help you.

1. each()
2. find()
3. :eq() Selector
4. text()
