title: Read a specific table column with Prototype
body: <p>I need to read all the values of the first column of an HTML table, and I don't want to use DOM methods. I'd like a simpler solution using Prototype or YUI. </p>
  
  <p>Note: the table is generated by a grid widget provided by an external team. That's why we cannot be sure of which IDs or Classnames are used. </p>
  
  <p>In short I'd like something like:</p>
  
  <pre><code>For each row in table XXX
     value = row.column[1].value
     do something with value ...
  End For
  </code></pre>
  
  <p>Thanks in advance</p>
