PySide + QTableView örneği

Question

Herkes beni PySide'deki basit bir QTableView örneğine yönlendirebilir mi?

QTableView docs'u buldum ama maalesef bir örnek vermiyorlar ve PySide için çok yeniyim, bu yüzden nasıl başlayacağımı bile bilmiyorum. (Java Swing JTable ile çok tanıdık, bu yüzden masa modellerini kullanmayı biliyorum.)

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
