Cgridview Header Combining

Is there a way to group columns in the header of a CGridview?

example:




+-----------------------------------------------------------------------+

|                 |                 |           Group Header            |

|    ColumnA      |    ColumnB      |-----------------------------------|

|                 |                 |     ColumnC     |     ColumnD     |

+-----------------------------------------------------------------------+

|        0        |       ...       |       ...       |      ...        |

+-----------------------------------------------------------------------+

|        1        |       ...       |       ...       |      ...        |

+-----------------------------------------------------------------------+

|        2        |       ...       |       ...       |      ...        |

+-----------------------------------------------------------------------+



I saw the groupgridview extension, but it does not give me this functionality.

thanks

just to answer my own question:

I found this: http://www.yiiframework.com/wiki/528/insert-a-multirow-header-in-cgridview/

edited it a small bit to support rowspan also.

that solved it.
