PyQT - Make integers and dates in QTableWidget properly sortable

[NewPyQt]

Hi.
I put the data into my QTableWidget tableView using a loop:

for i in range(0, len(res)):
                self.tableView.setItem(i, 2, QTableWidgetItem(str(create_dataframe(res)[2][i])))
                self.tableView.setItem(i, 3, QTableWidgetItem(str(create_dataframe(res)[3][i])))

where

create_dataframe(res)[2][i]

returns value of class 'int' and

create_dataframe(res)[3][i]

returns value of class 'datetime.datetime' (like '2017-03-25 16:51:24'). The question is: how do I make this items properly sortable through

self.tableView.setSortingEnabled(True)

, i.e. not as strings, but as integers and datetime respectively? I know that I should use setData and Qt.DisplayRole, but could you please give an example using this short piece of code?
Thank you.

Hi and welcome to devnet,

Do you mean that you want to sort your QTableWidget by the date string ?
