【Pyqt5】之高级控件QTableWidget的使用

1：动态渲染数据+动态添加控件（按钮，进度条）

class MainWindow(QWidget, Ui_MainFrom):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.setupUi(self)
        # #去掉标题头
        # self.setWindowFlags(Qt.FramelessWindowHint)
        # self.m_flag = False
        self.Button = QPushButton(self)
        self.Button.setGeometry(QtCore.QRect(880, 80, 93, 41))
        # 列表显示
        self.tableWidget.setColumnCount(5)
        # self.tableWidget.setRowCount(3)
        self.tableWidget.setHorizontalHeaderLabels(('视频网站','视频标题','播放地址','下载进度','操作',))
        self.tableWidget.setEditTriggers(QAbstractItemView.NoEditTriggers)  # 禁止编辑
        # 取数据库数据 输出来是个列表
        sortInfo = [('', 1, 1,),('', 1, 1, ),('', 1, 1,)]
        # 动态渲染数据
        for row, row_data in enumerate(sortInfo):
            self.tableWidget.insertRow(row)         # 插入行
            for column in range(len(row_data)+2):   # 需要多插入2列
                # 如果遍历数小于需要插入的函数，就显示空
                if column < len(row_data):
                    self.tableWidget.setItem(row, column, QtWidgets.QTableWidgetItem(str(row_data[column])))
                # 如果遍历数等于需要插入的函数
                if column == len(row_data):
                    # 传入当前id
                    print("row_data[0]",row+1)
                    # 添加两列 进度条 按钮
                    self.tableWidget.setCellWidget(row, column, self.ProgressBar(str(row_data[0])))
