title: capybara check if table column has some value
body: <p>I am new to Cucumber and Capybara and I have a table where I need to check if a specific column has some value.</p>
  
  <p>My step would be something like this: (in pseudocode)
  I should see something with value: A,B,C</p>
  
  <p>Then i need to query a table with a specific id and check if all the rows of the 2nd column have one the the values passed in the step.</p>
  
  <p>In this example this should pass the test</p>
  
  <pre><code>some value | A
  some value | B
  some value | A
  some value | A
  some value | C
  </code></pre>
  
  <p>but this wont pass:</p>
  
  <pre><code>some value | A
  some value | D
  </code></pre>
  
  <p>Any ideas?</p>
