Rubies Mechanize a stack of tables does not capture an entire row

I am trying to clear a table site mechanized. I want to clear the second line.

When I run:

agent.page.search('table.ea').search('tr')[-2].search('td').map{ |n| n.text }

I expect it to clear the entire line. But instead, these are just scratches: ["2011-02-17", "0.00"]

Why doesn't it clear all the columns in the row, but only the first and last columns?

Xpath: / HTML / body / center / table / TBODY / tr [2] / td [2] / table / TBODY / tr [3] / TD / table / TBODY / tr [2] / TD / table / TBODY / tr [2]

CSS PATH: html center center table tbody tr td table tbody tr td table tbody tr td table.ea tbody tr td.total

The page is similar to the following:

<table><table><table>
<table width="100%" border="0" cellpadding="0" cellspacing="1" class="ea">
<tr>
    <th><a href="#">Date</a></th>
    <th><a href="#">One</a></th>    
    <th><a href="#">Two</a></th>    
    <th><a href="#">Three</a></th>     
    <th><a href="#">Four</a></th>    
    <th><a href="#">Five</a></th>        
    <th><a href="#">Six</a></th>        
    <th><a href="#">Seven</a></th>      
    <th><a href="#">Eight</a></th>
