Pushbutton,点击Pushbutton后显示或隐藏第二个Widget。第二个Widget默认隐藏，第二个Widget包含三个TableWidget，每个tablewidget都是两列，其中TableWidget1与CheckBox1和CheckBox2对应,对应关系如下：CheckBox1对应TableWidget1中的CheckBox101,102,103，CheckBox2对应TableWidget1中的CheckBox201,202,203，根据CheckBox1和CheckBox2的勾选情况在table中第一列动态显示对应的CheckBox；第二列设置为comboBox,每个comboBox有两个选项；TableWidget2与CheckBoxA和CheckBoxB对应，对应关系如下：CheckBoxA对应TableWidget2中的CheckBoxA1,A2,A3，CheckBoxB对应TableWidget2中的CheckBoxB1,B2,B3，根据CheckBoxA和CheckBoxB的勾选情况在table中第一列动态显示CheckBox；第二列设置为comboBox,每个comboBox有两个选项；TableWidget3第一列为CheckBox：301,302,303和；第二列设置为comboBox,每个comboBox有两个选项。三个TableWidget下方设置一个Pushbutton,点击Pushbutton后依次print所有CheckBox和comboBox的值。

这是一个比较复杂的问题，需要用到PyQt5库来实现。以下是一个可供参考的实现代码：

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QPushButton, QTableWidget, QTableWidgetItem, QVBoxLayout, QHBoxLayout, QCheckBox, QComboBox

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

    def initUI(self):
        self.setGeometry(100, 100, 800, 600)
        self.setWindowTitle("Pushbutton Demo")

        self.gridLayout = QGridLayout()
        self.setLayout(self.gridLayout)

        self.pushButton = QPushButton('Show/Hide Widget')
        self.pushButton.clicked.connect(self.showHideWidget)
        self.gridLayout.addWidget(self.pushButton, 0, 0)

        self.widget2 = QWidget()
        self.widget2Layout = QVBoxLayout()
        self.widget2.setLayout(self.widget2Layout)

        self.tableWidget1 = QTableWidget()
        self.tableWidget1.setColumnCount(2)
        self.tableWidget1.setRowCount(3)
        self.tableWidget1.setHorizontalHeaderLabels(['Checkbox', 'Combobox'])

        for i in range(3):
            checkbox = QCheckBox('Checkbox1{}'.format(i+1))
            checkbox.stateChanged.connect(self.updateTable1)
            self.tableWidget1.setCellWidget(i, 0, checkbox)

            combobox = QComboBox()
            combobox.addItems(['Option1', 'Option2'])
            self.tableWidget1.setCellWidget(i, 1, combobox)

        self.widget2Layout.addWidget(self.tableWidget1)

        self.tableWidget2 = QTableWidget()
        self.tableWidget2.setColumnCount(2)
        self.tableWidget2.setRowCount(3)
        self.tableWidget2.setHorizontalHeaderLabels(['Checkbox', 'Combobox'])

        for i in range(3):
            checkbox = QCheckBox('CheckboxA{}'.format(i+1))
            checkbox.stateChanged.connect(self.updateTable2)
            self.tableWidget2.setCellWidget(i, 0, checkbox)

            combobox = QComboBox()
            combobox.addItems(['Option1', 'Option2'])
            self.tableWidget2.setCellWidget(i, 1, combobox)

        self.widget2Layout.addWidget(self.tableWidget2)

        self.tableWidget3 = QTableWidget()
        self.tableWidget3.setColumnCount(2)
        self.tableWidget3.setRowCount(3)
        self.tableWidget3.setHorizontalHeaderLabels(['Checkbox', 'Combobox'])

        for i in range(3):
            checkbox = QCheckBox('Checkbox30{}'.format(i+1))
            self.tableWidget3.setCellWidget(i, 0, checkbox)

            combobox = QComboBox()
            combobox.addItems(['Option1', 'Option2'])
            self.tableWidget3.setCellWidget(i, 1, combobox)

        self.widget2Layout.addWidget(self.tableWidget3)

        self.widget2Button = QPushButton('Print')
        self.widget2Button.clicked.connect(self.printValues)
        self.widget2Layout.addWidget(self.widget2Button)

        self.widget2.hide()
        self.gridLayout.addWidget(self.widget2, 1, 0)

    def showHideWidget(self):
        if self.widget2.isHidden():
            self.widget2.show()
        else:
            self.widget2.hide()

    def updateTable1(self):
        for i in range(3):
            checkbox = self.tableWidget1.cellWidget(i, 0)
            combobox = self.tableWidget1.cellWidget(i, 1)
            if checkbox.isChecked():
                combobox.show()
            else:
                combobox.hide()

    def updateTable2(self):
        for i in range(3):
            checkbox = self.tableWidget2.cellWidget(i, 0)
            combobox = self.tableWidget2.cellWidget(i, 1)
            if checkbox.isChecked():
                combobox.show()
            else:
                combobox.hide()

    def printValues(self):
        values = []
        for i in range(3):
            checkbox = self.tableWidget1.cellWidget(i, 0)
            combobox = self.tableWidget1.cellWidget(i, 1)
            if checkbox.isChecked():
                values.append('{}:{}'.format(checkbox.text(), combobox.currentText()))

        for i in range(3):
            checkbox = self.tableWidget2.cellWidget(i, 0)
            combobox = self.tableWidget2.cellWidget(i, 1)
            if checkbox.isChecked():
                values.append('{}:{}'.format(checkbox.text(), combobox.currentText()))

        for i in range(3):
            checkbox = self.tableWidget3.cellWidget(i, 0)
            combobox = self.tableWidget3.cellWidget(i, 1)
            if checkbox.isChecked():
                values.append('{}:{}'.format(checkbox.text(), combobox.currentText()))

        print(values)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = MyWidget()
    widget.show()
    sys.exit(app.exec_())

该代码实现了一个窗口，包含一个按钮和一个隐藏的Widget。点击按钮可以显示或隐藏该Widget。Widget中包含三个TableWidget和一个PushButton。每个TableWidget都包含两列，第一列为CheckBox，第二列为ComboBox。根据CheckBox的勾选情况，ComboBox可以动态显示或隐藏。点击PushButton会打印所有CheckBox和ComboBox的值。
