title: Rails/Capybara: How to click a link in a table row that also contains unique text
body: <p>I have an app that does not assign unique IDs to table cells. Given unique text in column 1, a manage link in column 2, and a delete link in column 3, how do I tell capybara to click the manage link in the same row that contains the text 'Foo'?</p>
  
  <pre><code>Foo   manage  delete
  Bar   manage  delete
  </code></pre>
  
  <p>I see how to use <code>find('tr', text: "Foo")</code> when used with a <code>.should</code> clause. And I see how to click a link that contains the text 'manage'. But I do not see how to combine them tofind a row, and within that row, click a link.</p>
