用pyside6库写一个界面。界面中第一行有2个checkbutton1,2,第二行有2个checkbutton3,4.第三行设一个pushbutton,点击pushbutton后在第四行设一个tablewidget,tablewidget有两列,根据checkbutton1,2的勾选情况动态添加行数row1,2;根据checkbutton3,4的勾选情况再tablewidget的第二列添加下拉选项option3,4.

可以按照以下步骤来实现:
1. 导入PySide6库中的必要模块:
```python
from PySide6.QtWidgets import QApplication, QWidget, QCheckBox, QVBoxLayout, QPushButton, QTableWidget, QTableWidgetItem, QComboBox
```
2. 创建一个QWidget窗口并设置其布局为QVBoxLayout:
```python
app = QApplication([])
window = QWidget()
layout = QVBoxLayout()
window.setLayout(layout)
```
3. 创建2个QCheckBox控件并将其添加到窗口的第一行布局中:
```python
check1 = QCheckBox('Checkbox 1')
check2 = QCheckBox('Checkbox 2')
layout.addWidget(check1)
layout.addWidget(check2)
```
4. 创建另外2个QCheckBox控件并将其添加到窗口的第二行布局中:
```python
check3 = QCheckBox('Checkbox 3')
check4 = QCheckBox('Checkbox 4')
layout.addWidget(check3)
layout.addWidget(check4)
```
5. 创建一个QPushButton控件并将其添加到窗口的第三行布局中:
```python
button = QPushButton('Add Rows')
layout.addWidget(button)
```
6. 创建一个QTableWidget控件,并将其添加到窗口的第四行布局中:
```python
table = QTableWidget()
table.setColumnCount(2)
layout.addWidget(table)
```
7. 创建一个函数,用于根据check1和check2的勾选情况动态添加行数row1和row2:
```python
def update_rows():
table.setRowCount(0)
if check1.isChecked():
table.setRowCount(table.rowCount() + 1)
if check2.isChecked():
table.setRowCount(table.rowCount() + 1)
```
8. 创建一个函数,用于根据check3和check4的勾选情况向tablewidget的第二列添加下拉选项option3和option4:
```python
def update_comboboxes():
for row in range(table.rowCount()):
combobox = QComboBox()
if check3.isChecked():
combobox.addItem('Option 3')
if check4.isChecked():
combobox.addItem('Option 4')
table.setCellWidget(row, 1, combobox)
```
9. 将update_rows函数连接到button的clicked信号,将update_comboboxes函数连接到check3和check4的stateChanged信号:
```python
button.clicked.connect(update_rows)
check3.stateChanged.connect(update_comboboxes)
check4.stateChanged.connect(update_comboboxes)
```
10. 在update_rows函数中添加代码以向tablewidget的第一列添加行号:
```python
def update_rows():
table.setRowCount(0)
if check1.isChecked():
row = table.rowCount()
table.setRowCount(row + 1)
item = QTableWidgetItem(str(row + 1))
table.setItem(row, 0, item)
if check2.isChecked():
row = table.rowCount()
table.setRowCount(row + 1)
item = QTableWidgetItem(str(row + 1))
table.setItem(row, 0, item)
```
11. 显示窗口并启动应用程序:
```python
window.show()
app.exec_()
```
完整代码如下:
```python
from PySide6.QtWidgets import QApplication, QWidget, QCheckBox, QVBoxLayout, QPushButton, QTableWidget, QTableWidgetItem, QComboBox
app = QApplication([])
window = QWidget()
layout = QVBoxLayout()
window.setLayout(layout)
check1 = QCheckBox('Checkbox 1')
check2 = QCheckBox('Checkbox 2')
layout.addWidget(check1)
layout.addWidget(check2)
check3 = QCheckBox('Checkbox 3')
check4 = QCheckBox('Checkbox 4')
layout.addWidget(check3)
layout.addWidget(check4)
button = QPushButton('Add Rows')
layout.addWidget(button)
table = QTableWidget()
table.setColumnCount(2)
layout.addWidget(table)
def update_rows():
table.setRowCount(0)
if check1.isChecked():
row = table.rowCount()
table.setRowCount(row + 1)
item = QTableWidgetItem(str(row + 1))
table.setItem(row, 0, item)
if check2.isChecked():
row = table.rowCount()
table.setRowCount(row + 1)
item = QTableWidgetItem(str(row + 1))
table.setItem(row, 0, item)
def update_comboboxes():
for row in range(table.rowCount()):
combobox = QComboBox()
if check3.isChecked():
combobox.addItem('Option 3')
if check4.isChecked():
combobox.addItem('Option 4')
table.setCellWidget(row, 1, combobox)
button.clicked.connect(update_rows)
check3.stateChanged.connect(update_comboboxes)
check4.stateChanged.connect(update_comboboxes)
window.show()
app.exec_()
```
