How do I get the tds in the second row of a table?

Hello,
I'm new to jquery and I'm trying to get the data in the second row of a table, but I can't figure it out.

I can get the first row with:

$(this).parents("tr:first").find("td:nth-child(2)").text();

But I can't figure out how to get the second row. Any help would be appreciated.

Thank you.

David
