Loop in table with Watir - watir

Question

Stuck with watir trying to create a loop to click in all the links included in a table. Currently the table has this format:
<table id="test">
<tbody><tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Link</th>
</tr>
<tr>
<td>Jill</td>
<td>Smith</td>
<td>http://facebook.com</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>http://google.com</td>
</tr>
</tbody></table>
And my current attempt looks like:
browser.table(:id => "test").rows do |tr|
tr.each do |td|
td.links.click
end
end
This code above does nothing in the browser & neither returns something in the terminal (no errors, no outputs).
Also tried a different approach using columns:
columns = browser.table(:id => "test").strings.transpose
browser.columns.each do |t|
t.click
browser.back
end
That outputs this error: jsfiddle.rb:24:in <main>': undefined methodcolumns' for # (NoMethodError)

Answer 1

The newer versions of Watir, version 6.0, automatically attempts to relocate stale elements. As a result, as long as the initial page does not change each time you reload it, you no longer need to save some sort of reference data before clicking the links.
It simply becomes:
my_table = browser.table(:id, 'test')
my_table.links.each do |link|
link.click
browser.back
end

Answer 2

This should work to click on each link in the table:
my_table = browser.table(:id, 'test')
table_links = my_table.links.map(&:text)
table_links.each do |link_text|
my_table.link(:text, link_text).click
browser.back
end
Largely based on Justin Ko's answer here.
