QTableWidget, копировать данные между таблицами

Question

Есть небольшое приложение сделанное с помощью Qt Designer, в нем есть две таблицы QTableWidget с некими данными (DataTable_1, DataTable_2).

Нашел подходящие мне решение(https://quares.ru/?id=193989), но к сожалению не могу его правильно применить для себя.

Вот так я сделал:

import sys
from PyQt5 import QtWidgets, QtCore
import design

class ExampleApp(QtWidgets.QMainWindow, design.Ui_MainWindow):
def __init__(self):
    super().__init__()
    self.setupUi(self)
    self.deleteRow_1.clicked.connect(self.delete_row_1)
    self.addRow_1.clicked.connect(self.add_row_1)
    self.deleteRow_2.clicked.connect(self.delete_row_2)
    self.addRow_2.clicked.connect(self.add_row_2)

def keyPressEvent(self, event):
    super().keyPressEvent(event)
    if event.key() == QtCore.Qt.Key_C and (event.modifiers() & QtCore.Qt.ControlModifier):
        self.DataTable_1.copied_cells = sorted(self.DataTable_1.selectedIndexes())
    elif event.key() == QtCore.Qt.Key_V and (event.modifiers() & QtCore.Qt.ControlModifier):
        r = self.DataTable_1.currentRow() - self.DataTable_1.copied_cells[0].row()
        c = self.DataTable_1.currentColumn() - self.DataTable_1.copied_cells[0].column()
        for cell in self.DataTable_1.copied_cells:
            self.DataTable_1.setItem(cell.row() + r, cell.column() + c, QtWidgets.QTableWidgetItem(cell.data()))

def add_row_1(self):
    row_position = self.DataTable_1.rowCount()
    self.DataTable_1.insertRow(row_position)

def delete_row_1(self):
    rows = set()
    for index in self.DataTable_1.selectedIndexes():
        rows.add(index.row())
    for row in sorted(rows, reverse=True):
        self.DataTable_1.removeRow(row)

def add_row_2(self):
    row_position = self.DataTable_2.rowCount()
    self.DataTable_2.insertRow(row_position)

def delete_row_2(self):
    rows = set()
    for index in self.DataTable_2.selectedIndexes():
        rows.add(index.row())
    for row in sorted(rows, reverse=True):
        self.DataTable_2.removeRow(row)

def main():
    app = QtWidgets.QApplication(sys.argv)
    window = ExampleApp()
    window.show()
    app.exec_()


if __name__ == '__main__':
    main()

Код на pastebin design.py

С таблицей DataTable_1 все работает как нужно, но я не могу сделать тоже самое для таблицы DataTable_2. В идеале также хотелось бы чтобы данные можно было копировать между таблицами. Спасибо.
