PyQt, Qtable clears column when sorting enabled

Question

I have a bug in next function. This function refreshes table with, adjust column sizes and sorts table. But in some cases for some rows text in column 3 and 4 is empty. I found out, that it happens in "problem code" section. What do i wrong in this section? I just want to change size for specific columns. Please help to find out the problem or show me my mistakes.

def print_day_worklog(self):
    logging.info('RefReshing day worklog table')
    selected_day = self.ui.dateDayWorklogEdit.date().toPyDate()
    day_work = db.get_day_worklog(self.creds[3], selected_day)
    self.ui.tableDayWorklog.setRowCount(len(day_work))
    for row, entry in enumerate(day_work):
        e0 = QtGui.QTableWidgetItem(entry[0])
        e1 = QtGui.QTableWidgetItem(entry[1])
        e2 = QtGui.QTableWidgetItem(entry[2].strftime('%H:%M'))
        e3 = QtGui.QTableWidgetItem(entry[3].strftime('%H:%M'))
        e4 = QtGui.QTableWidgetItem(utils.get_time_spent_string(entry[2],
            entry[3]))
        # debug
        print e0.text(), e1.text(), e2.text(), e3.text(), e4.text()
        self.ui.tableDayWorklog.setItem(row, 0, e0)
        self.ui.tableDayWorklog.setItem(row, 1, e1)
        self.ui.tableDayWorklog.setItem(row, 2, e2)
        self.ui.tableDayWorklog.setItem(row, 3, e3)
        self.ui.tableDayWorklog.setItem(row, 4, e4)

    # problem code starts
    self.ui.tableDayWorklog.horizontalHeader().setResizeMode(1,
        QtGui.QHeaderView.Stretch)
    for column in (0,2,3,4):
        self.ui.tableDayWorklog.resizeColumnToContents(column)
        self.ui.tableDayWorklog.horizontalHeader().setResizeMode(column,
            QtGui.QHeaderView.Fixed)
        self.ui.tableDayWorklog.horizontalHeader().setResizeMode(column,
            QtGui.QHeaderView.Fixed)
    self.ui.tableDayWorklog.sortByColumn(2,0)
    # problem code ends

P.s. it looks not clearly, but it's because i try to catch the bug

Problem is in table sorting. I've found this idea in this question. I've just added

self.ui.tableDayWorklog.setSortingEnabled(False)

before filling the table and this

self.ui.tableDayWorklog.setSortingEnabled(True)

after that. and it helped
