PySide + QTableView Beispiel

Question

Kann mir jemand auf ein einfaches Beispiel von QTableView in PySide zeigen?

Ich fand die QTableView docs aber leider geben sie kein Beispiel, und ich bin PySide sehr neu, so dass ich nicht einmal weiß, wie ich anfangen soll. (Ich bin sehr vertraut mit der JTable in Java Swing, damit ich weiß, wie Tischmodelle verwenden.)

''' ps_QAbstractTableModel_solvents.py 
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
