我基于 QAbstractTableModel 创建一个类“pandasModel”，如下所示：

import sys
from PyQt5.QtGui     import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore    import *
class pandasModel(QAbstractItemModel):

    def __init__(self, data, parent=None):
        QAbstractItemModel.__init__(self, parent)
        self._data = data

    def rowCount(self, parent=None):
        return self._data.index.size

    def columnCount(self, parent=None):
        return self._data.columns.size

    def data(self, index, role=Qt.DisplayRole):
        if index.isValid():
            if role == Qt.DisplayRole:
                return str(self._data.iloc[index.row(), index.column()])
            if role == Qt.EditRole:
                return str(self._data.iloc[index.row(), index.column()])
        return None

    def headerData(self, rowcol, orientation, role):
        if orientation == Qt.Horizontal and role == Qt.DisplayRole:
            return self._data.columns[rowcol]
        if orientation == Qt.Vertical and …
