PySide + QTableViewの例

Question

PySideのQTableViewの簡単な例を教えてもらえますか？

私はQTableView docsを見つけましたが、残念なことにそれらは例を挙げていません。私はPySideを非常に新しくしています。 （Iは、JavaのSwingでJTableのに非常に精通していますので、私は、テーブルモデルを使用する方法を知っている。）

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
