无法遍历QTableWidget的列

我需要一些帮助,因为这个问题根本没有道理...缩进看起来有点抱歉...

self.myData = [["facebook-icon", "Facebook", str(self.mykeys[0][1]), "*" *len(self.passes[0])], ......

即使rowCount打印出数字3,也仅填充表中的第一项。那就是让我感到困惑的..希望有人尝试这段代码,我是Python新手

    passAmount = len(self.myData)
    print("There are %x items in myData" % (passAmount))

    rowCount = self.tableWidget.rowCount()
    print("There are %x items in the table" % (rowCount))

    for row in range(0, rowCount):
        cellText = self.tableWidget.itemAt(row,0).text()

        if(cellText == "facebook-icon"):
            self.tableWidget.itemAt(row, 0).setText("")
            print(imagePaths[0])
            fb = QPixmap(imagePaths[0]).scaledToWidth(20)
            label = QLabel()

            label.setPixmap(fb)

            # label.setScaledContents(True)
            self.tableWidget.setCellWidget(row, 0, label)


        elif(cellText == "blogger-icon"):
            ...


    self.tableWidget.setFont(self.font)
    self.tableWidget.resizeColumnsToContents()
    self.tableWidget.resizeRowsToContents()
    self.tableWidget.doubleClicked.connect(self.on_table_click)



    # Show widget
    self.show()

我做错什么了吗?

如我所见,您想从第一列中获取元素,但是itemAt()不会将给定行和列的项返回到几何位置,而是应使用item()方法。另外,我们可以使用字典来减少代码:

dict_icons = {
    "facebook-icon": imagePaths[0],
    "blogger-icon": imagePaths[1]
}

for row in range(0, 3):
    item = self.tableWidget.item(row, 0)
    image_path =  dict_icons.get(item.text())
    if image_path is not None:
        item.setText("")
        pixmap = QPixmap(image_path).scaledToWidth(20)
        label = QLabel(pixmap=pixmap)
        self.tableWidget.setCellWidget(row, 0, label)
