无法填充tablewidget的某些单元格。 PyQt5

Question

I'm programming a simple csv handler that will just look at two columns using python 3.7.2 and pyqt5. It will have a desired number of rows and all of them needs to be filled for my program to work. But when I run my loops only 11 out of 20 cells get filled. When I decrease the row count to 10 this ratio is 6/10 and for 6 this is 4/6. I can't find why this occurs.

Here is the loop that sets the headers firstly.

x = 0
    while x<total_rows:
        item = QtWidgets.QTableWidgetItem()
        self.tableWidget.setVerticalHeaderItem(x, item)
        x+=1

This is the loop that fills the first column with zeros.

x = 0
    while x<total_rows:
        print(x)
        self.tableWidget.setItem(0,x, QtWidgets.QTableWidgetItem("0"))
        x+=1

And this is the loop that fills the second column with zeros.

x = 0
    while x<total_rows:
        print(x)
        self.tableWidget.setItem(1,x, QtWidgets.QTableWidgetItem("0"))
        x+=1

For other details that you may need when you are solving my problems here is the whole code. (I have no file sharing platforms available right now. Please accept my apologies for sharing the whole code in text.)

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

I put the print statements if my loops were just wrong. I checked and all loops run 20 times (As the x values reach 19 everytime).

Edit: It seems like double-digits are the problem.But this syntax is surely true according to the documentation.

self.tableWidget.setItem(1,10, QtWidgets.QTableWidgetItem("0"))

Answer 1

You changed rows with columns

# ...
        x = 0
        while x < total_rows:
# ---            self.tableWidget.setItem(0, x, QtWidgets.QTableWidgetItem("0")) 
            self.tableWidget.setItem(x, 0, QtWidgets.QTableWidgetItem("0"))     # +++
            x += 1

        x = 0
        while x<total_rows:
# ---           self.tableWidget.setItem(1,x, QtWidgets.QTableWidgetItem("0"))
            self.tableWidget.setItem(x, 1, QtWidgets.QTableWidgetItem("0"))     # +++
            x += 1

# ...
