title: jQuery selector to grab cells in the same column
body: <p>Given a multirow, multicolumn table, how can I select all cells in the same <em>column</em> as any arbitrary cell (e.g. a cell that is clicked on).</p>
  
  <p>Something like:</p>
  
  <pre><code>$("td").click(function(){
      var columnNo = $(this).columnNo?
      $(this).closest("table").find("tr td:eq("+columnNo+")").css("color", "red");
  });
  </code></pre>
  
  <p>I need to do this without naming the columns individually. E.g. it should work on simple generic <code>table</code> markup without extra classes or IDs..</p>
