Question

We can select multiple items(partial rows and partial columns) from QTableView using self.tableView.setSelectionMode(QAbstractItemView.ExtendedSelection), but a

Answer 1

self.tableView.installEventFilters(self)

Now, adding event filter:

def eventFilter(self, source, event):
        if (event.type() == QtCore.QEvent.KeyPress and
            event.matches(QtGui.QKeySequence.Copy)):
            self.copySelection()
            return True
        return super(Window, self).eventFilter(source, event)

Copy Function:

def copySelection(self):
        selection = self.tableView.selectedIndexes()
        if selection:
            rows = sorted(index.row() for index in selection)
            columns = sorted(index.column() for index in selection)
            rowcount = rows[-1] - rows[0] + 1
            colcount = columns[-1] - columns[0] + 1
            table = [[''] * colcount for _ in range(rowcount)]
            for index in selection:
                row = index.row() - rows[0]
                column = index.column() - columns[0]
                table[row][column] = index.data()
            stream = io.StringIO()
            csv.writer(stream).writerows(table)
            QtGui.qApp.clipboard().setText(stream.getvalue())
