If I create the following template based on your code it runs fine.  It 
may be a problem with whatever your 'plates' object is in the second 
tal:repeat.

<html>
  <head>
    <title tal:content="template/title">The title</title>
  </head>
  <body>
  <table>
    <div tal:define="plates string:slkfdjlskdjfldskjsdfsdfsdfsdff">
      <tr tal:repeat="row python:range(2)">
        <td align="center" tal:repeat="plate python:plates[row * 2:(row* 
2) + 2]">
          <div tal:replace="plate"></div>
        </td>
      </tr>
    </div>
  </table>
  </body>
</html>
