Hi Valentino,
thank you for quick response, but this is not the target! Your recipe will results in:
   | name | age |
   | name | age |
   ...
table, but I'm looking for a table result like:
   | name IS age | name IS age | name IS age |
   ...
   | name IS age | name IS age | <empty> |

The trick should be to get more (i.e. 3) data-sets into 1 row !

Is there a way?
