如何用pyqt中的数据快速填充QTableView/Model

from PyQt5.QtWidgets import QApplication, QTableView
from PyQt5.QtCore import Qt, QAbstractTableModel

class MyTableModel(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.data[0])

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

    def headerData(self, section, orientation, role):
        if role == Qt.DisplayRole:
            if orientation == Qt.Horizontal:
                return str(self.headers[section])
            else:
                return str(section + 1)

app = QApplication([])
table = QTableView()

data = [
    [1, 'John', 25],
    [2, 'Jane', 30],
    [3, 'Tom', 35]
]
headers = ['ID', 'Name', 'Age']

model = MyTableModel(data, headers)
table.setModel(model)

table.horizontalHeader().setStretchLastSection(True)
table.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)

table.show()
app.exec()
