无法填充表小部件的某些单元格。PyQt5

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem, QVBoxLayout, QWidget

app = QApplication([])

table = QTableWidget(3, 2)
table.setHorizontalHeaderLabels(['Column 1', 'Column 2'])

# 正确填充数据
item1 = QTableWidgetItem('Hello')
item2 = QTableWidgetItem(123)
table.setItem(0, 0, item1)
table.setItem(0, 1, item2)

window = QWidget()
layout = QVBoxLayout(window)
layout.addWidget(table)
window.setLayout(layout)
window.show()

app.exec_()

# 错误的索引示例
# table.setItem(5, 0, QTableWidgetItem('Out of range'))

# 正确的索引示例
table.setItem(2, 0, QTableWidgetItem('Correct index'))

table.setRowCount(3)
table.setColumnCount(2)
