無法填充tablewidget的某些單元格。 PyQt5

Question

我正在編寫一個簡單的csv處理程序，它只使用python 3.7.2和pyqt5來查看兩列。 它將具有所需的行數，並且需要填充所有行以使我的程序正常工作。 但是當我運行我的循環時，20個單元中只有11個被填滿。 當我將行數減少到10時，此比率為6/10，而對於6，這是4/6。 我找不到為什么會這樣。

這是首先設置標頭的循環。

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

這是用零填充第一列的循環。

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

這是用零填充第二列的循環。

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

在解決我的問題時，您可能需要的其他細節是整個代碼。 （我現在沒有可用的文件共享平台。請接受我在文本中共享整個代碼的道歉。）

if __name__ == "__main__":

    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

如果我的循環錯誤，我把print語句。 我檢查了所有循環運行20次（因為x值每次達到19）。

編輯：似乎兩位數是問題。但根據文檔，這種語法肯定是正確的。

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

Answer 1

您使用列更改了行

# ...
        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

# ...
