在QTable中打开CSV文件时程序关闭

Question

when I added function for a button to show data in CSV file when I click the program, it closes itself. I altered my code, however, the same problem persists.

Debug does not show any error messages. I'm a beginner in qt and if there alternatives to qtablewidget or better ways to tackle this, please let me know.

I do not understand why you use QTextTableCellFormat , QTableWidget expects a QTableWidgetItem :

def open_csv(self):
    self.tableWidget.setRowCount(0)
    with open(self.fname , 'r') as record :
        for row_data in csv.reader(record):
            row = self.tableWidget.rowCount()
            self.tableWidget.insertRow(row)
            for col , data in enumerate(row_data):
                item = QtWidgets.QTableWidgetItem(data)
                self.tableWidget.setItem( row , col, item)
