jqgrid + treegrid + subgrid

I wonder, is it possible to treegrid and subgrid together. For example:

-----------------------------
|   foo    |  bar  |  buz   | -> this is treegrid
----------------------------- 
-   foo_1   bar_1   buz_1
--  foo_1.1 bar_1.2 buz_1.3
--  foo_1.4 bar_1.5 buz_1.6 
-   foo_2   bar_2   buz_2
--  foo_2.1 bar_2.2 buz_2.3
-- -------------------------
-- |   a  |   b   |   c    |
-- -------------------------
---    1      2       3
---    4      5       开发者_开发问答6       -> this is subgrid for "foo_2.1 bar_2.2 buz_2.3" row
---    7      8       9
   -------------------------
-   foo3    bar3    buz3

thanks for any help!!!
