Set the same header to two columns

Hi everybody, I would like to know if I can set for two columns the same header, like that:

_________________________________
|###########A header |
|--------------------------------------------|
|######### | column 1 | # column 2|
|--------------------------------------------|
| Item 1 #### | ## 9 ##| ### 4 #|
| Item 2 #### | ## 5 ##| ### 2 #|
| Item 3 #### | ## 2 ##| ### 11 #|
| Item 4 #### | ## 12 ##| ### 9 #|
|======================== |

I know I am a profissional in ascii drawing ;)

Well, is that possible in qt?


Thanks in advanced
