使用PyQt5将异步数据添加到QTableView

from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView
from PyQt5.QtCore import QAbstractTableModel, Qt, QThread, pyqtSignal

class CustomTableModel(QAbstractTableModel):
    def __init__(self, data, headers):
        super().__init__()
        self.data = data
        self.headers = headers

    def rowCount(self, parent):
        return len(self.data)

    def columnCount(self, parent):
        return len(self.headers)

    def data(self, index, role):
        if role == Qt.DisplayRole:
            row = index.row()
            col = index.column()
            return self.data[row][col]

    def headerData(self, section, orientation, role):
        if role == Qt.DisplayRole:
            if orientation == Qt.Horizontal:
                return self.headers[section]

class Worker(QThread):
    dataReady = pyqtSignal(list)

    def __init__(self):
        super().__init__()

    def run(self):
        # 异步获取数据的逻辑
        data = self.fetchData()
        self.dataReady.emit(data)

    def fetchData(self):
        # 异步获取数据的具体实现
        # 返回一个包含数据的列表
        pass

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.table = QTableView()
        self.setCentralWidget(self.table)

        self.worker = Worker()
        self.worker.dataReady.connect(self.updateTable)

        self.worker.start()

    def updateTable(self, data):
        headers = ['Column 1', 'Column 2', 'Column 3']  # 列名
        model = CustomTableModel(data, headers)
        self.table.setModel(model)

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()
