How set QtableView stretching background image

[aguayro]

My app has a QTablwView, I can set the background image with StyleSheet or with QPalette, but can't get the image stretching to the QTableView, only repeat and no-repeat, but can't find a way to set it to stretch.

any help please?
I've been searching in google for some hours, but nothing found...
