Exemple PySide + QTableView

Quelqu'un peut-il m'indiquer un exemple simple de QTableView dans PySide?

J'ai trouvé les QTableView docs mais malheureusement, ils ne donnent pas d'exemple, et je suis très novice dans PySide, donc je ne sais même pas comment commencer. (Je connais très bien JTable dans Java Swing, je sais donc comment utiliser les modèles de table.)

use PySide's QTableView and QAbstractTableModel for tabular data
sort columns by clicking on the header title
here applied to solvents commonly used in Chemistry
