如何在QTableView的列中显示下拉列表并根据下拉列表进行过滤

class ComboBoxDelegate(QStyledItemDelegate):
    def paint(self, painter, option, index):
        options = QStyleOptionComboBox()
        options.rect = option.rect
        options.currentText = index.data()
        options.state = QStyle.State_Enabled
        if option.state & QStyle.State_Selected:
            options.state |= QStyle.State_Selected
        QApplication.style().drawComplexControl(QStyle.CC_ComboBox, options, painter)

    def createEditor(self, parent, option, index):
        editor = QComboBox(parent)
        editor.addItems(index.data())
        return editor

table_view = QTableView()
delegate = ComboBoxDelegate()
table_view.setItemDelegateForColumn(column_index, delegate)

model = QStandardItemModel()
table_view.setModel(model)

# 填充数据
for row in range(row_count):
    for column in range(column_count):
        item = QStandardItem(data[row][column])
        model.setItem(row, column, item)

class FilterProxyModel(QSortFilterProxyModel):
    def __init__(self, parent=None):
        super(FilterProxyModel, self).__init__(parent)
        self.filters = {}

    def setFilter(self, column, value):
        self.filters[column] = value
        self.invalidateFilter()

    def filterAcceptsRow(self, source_row, source_parent):
        model = self.sourceModel()
        for column, value in self.filters.items():
            index = model.index(source_row, column, source_parent)
            if index.data() != value:
                return False
        return True

filter_proxy_model = FilterProxyModel()
filter_proxy_model.setSourceModel(model)
table_view.setModel(filter_proxy_model)

editor = QComboBox()
editor.addItems(['Option 1', 'Option 2', 'Option 3'])
editor.currentIndexChanged.connect(lambda: filter_proxy_model.setFilter(column_index, editor.currentText()))
