使用pyqt5的tableview的view model 委托对数据读取写入的示例代码

当然可以，以下是一个简单的示例：

from PyQt5 import QtWidgets, QtCore

class MyDelegate(QtWidgets.QStyledItemDelegate):
    def createEditor(self, parent, option, index):
        editor = QtWidgets.QLineEdit(parent)
        return editor

    def setEditorData(self, editor, index):
        value = index.model().data(index, QtCore.Qt.DisplayRole)
        editor.setText(str(value))

    def setModelData(self, editor, model, index):
        value = editor.text()
        model.setData(index, value, QtCore.Qt.EditRole)

class MyTableModel(QtCore.QAbstractTableModel):
    def __init__(self, data):
        super().__init__()
        self._data = data

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

    def setData(self, index, value, role=QtCore.Qt.EditRole):
        if role == QtCore.Qt.EditRole:
            self._data[index.row()][index.column()] = value
            self.dataChanged.emit(index, index)
            return True
        return False

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

    def columnCount(self, parent):
        return len(self._data[0])

if __name__ == '__main__':
    import sys

    data = [[1, 2], [3, 4]]

    app = QtWidgets.QApplication(sys.argv)

    view = QtWidgets.QTableView()
    model = MyTableModel(data)
    view.setModel(model)
    delegate = MyDelegate()
    view.setItemDelegate(delegate)
    view.show()

    sys.exit(app.exec_())
