from PyQt5.QtWidgets import QTableWidget, QTableWidgetItem # Create a new QTableWidget with 3 rows and 2 columns table = QTableWidget(3, 2) # Add an item to each cell for row in range(table.rowCount()): for col in range(table.columnCount()): item = QTableWidgetItem(str(row) + ' ' + str(col)) # create new QTableWidgetItem with data table.setItem(row, col, item) # set the item in the table # Add a new row to the table row = table.rowCount() # get the current number of rows table.insertRow(row) # add a new row at the end item1 = QTableWidgetItem('New Row Data') # create new QTableWidgetItem with data item2 = QTableWidgetItem('More Data') # create new QTableWidgetItem with data table.setItem(row, 0, item1) # add first QTableWidgetItem table.setItem(row, 1, item2) # add second QTableWidgetItemThis code creates a new `QTableWidget` with 3 rows and 2 columns, then adds an item to each cell. Next, a new row is added to the end of the table with two new items using `QTableWidgetItem`. In summary, the `PyQt5.QtWidgets.QTableWidgetItem` is a class used to display data in a cell in a `QTableWidget`, and it's a part of the `PyQt5.QtWidgets` package/library in Python.
