如何将 Excel 选定行和列中的值粘贴到 PYQT5 中的 Qtablewidget

如何解决如何将 Excel 选定行和列中的值粘贴到 PYQT5 中的 Qtablewidget

下面是我得到的代码供参考。在这里，我可以在应用程序中复制和粘贴选定的值。 但就我而言，我想在 excel 中复制某些单元格的值（假设为 A4:D6）并将其粘贴到此应用程序的 Qtableview 中。

我也尝试过 qclipboard 和其他选项，但没有奏效。它只是将所有单元格复制到应用程序中 Qtableview 的单元格中。但是应该和excel一样填写。

我几乎浏览了许多选项，但找不到任何解决方案。请支持
