QTablewidget setcurrwidget设置多个不重叠

您可以使用QTableWidget的setCellWidget方法来设置多个不重叠的单元格小部件。以下是一个示例代码：

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem, QPushButton, QWidget, QHBoxLayout
import sys

class Example(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.setGeometry(300, 300, 350, 300)
        self.setWindowTitle('QTableWidget Example')

        # Create a QTableWidget object
        self.table_widget = QTableWidget(self)
        self.table_widget.setGeometry(50, 50, 250, 200)
        self.table_widget.setColumnCount(2)
        self.table_widget.setRowCount(3)

        # Create QPushButton objects and add them to the table
        button1 = QPushButton("Button 1")
        button2 = QPushButton("Button 2")
        button3 = QPushButton("Button 3")

        # Create QHBoxLayout objects to add the buttons to
        layout1 = QHBoxLayout()
        layout2 = QHBoxLayout()
        layout3 = QHBoxLayout()

        # Add the buttons to the layouts
        layout1.addWidget(button1)
        layout2.addWidget(button2)
        layout3.addWidget(button3)

        # Create QWidget objects to hold the QHBoxLayouts
        widget1 = QWidget()
        widget2 = QWidget()
        widget3 = QWidget()

        # Set the QHBoxLayouts as the layouts for the QWidgets
        widget1.setLayout(layout1)
        widget2.setLayout(layout2)
        widget3.setLayout(layout3)

        # Add the QWidgets to the table using setCellWidget
        self.table_widget.setCellWidget(0, 0, widget1)
        self.table_widget.setCellWidget(1, 0, widget2)
        self.table_widget.setCellWidget(2, 0, widget3)

        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

在此示例中，我们创建了一个QTableWidget对象，并将其添加到QWidget对象中。我们然后创建三个QPushButton对象，并将它们添加到每个QHBoxLayout对象中。我们然后创建三个QWidget对象，并将每个QHBoxLayout设置为其布局。最后，我们使用setCellWidget方法将这三个QWidget对象添加到QTableWidget的不同单元格中。这样，我们就可以在三个不同的单元格中看到三个不同的按钮。
