jQuery - How to combine multiple elements with same class name in one selector?
===

Sorry about the cranky title, here's the example:

    <table>
      <tr class="hey-1-aa">...</tr>
      <tr class="hey-2-aa">...</tr>
      <tr class="hey-1-bb">...</tr>
      <tr class="hey-2-bb">...</tr>
    </table>

Is there any better way to selects all the THs/TRs with the class "hey-2", with something less verbose than `$('th[class^="hey-2"], td[class^="hey-2"]')`?
