我想在PyQt5的QtableView中显示csv文件

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

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

    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:
            row = index.row()
            col = index.column()
            return str(self.data[row][col])
        return None

class MainWindow(QMainWindow):
    def __init__(self, data):
        super().__init__()
        self.table_view = QTableView(self)
        self.setCentralWidget(self.table_view)
        self.model = TableModel(data)
        self.table_view.setModel(self.model)

def read_csv(file_path):
    data = []
    with open(file_path, 'r') as file:
        reader = csv.reader(file)
        for row in reader:
            data.append(row)
    return data

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