使Enter键的行为类似于QTableWidget中的制表符

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem
from PyQt5.QtCore import Qt

class CustomTableWidget(QTableWidget):
    def keyPressEvent(self, event):
        if event.key() == Qt.Key_Return or event.key() == Qt.Key_Enter:
            current_row = self.currentRow()
            current_column = self.currentColumn()
            next_column = current_column + 1
            next_row = current_row
            if next_column >= self.columnCount():
                next_column = 0
                next_row += 1
            if next_row >= self.rowCount():
                next_row = 0
            self.setCurrentCell(next_row, next_column)
        else:
            super().keyPressEvent(event)

# 创建一个QTableWidget实例
table_widget = CustomTableWidget()

# 添加行和列
table_widget.setRowCount(3)
table_widget.setColumnCount(3)

# 设置单元格内容
table_widget.setItem(0, 0, QTableWidgetItem("Cell 1"))
table_widget.setItem(0, 1, QTableWidgetItem("Cell 2"))
table_widget.setItem(0, 2, QTableWidgetItem("Cell 3"))
table_widget.setItem(1, 0, QTableWidgetItem("Cell 4"))
table_widget.setItem(1, 1, QTableWidgetItem("Cell 5"))
table_widget.setItem(1, 2, QTableWidgetItem("Cell 6"))
table_widget.setItem(2, 0, QTableWidgetItem("Cell 7"))
table_widget.setItem(2, 1, QTableWidgetItem("Cell 8"))
table_widget.setItem(2, 2, QTableWidgetItem("Cell 9"))

# 显示表格
table_widget.show()

# 运行应用程序
app = QApplication([])
app.exec_()
