你可以在 `TabWidget` 类中添加一个按钮，并连接到一个槽函数来关闭当前的 `HtmlView`。以下是修改后的代码：

from PySide2.QtCore import *
from PySide2.QtWidgets import *
from PySide2.QtWebEngineWidgets import *

class TabWidget(QTabWidget):
    def __init__(self, *args, **kwargs):
        QTabWidget.__init__(self, *args, **kwargs)
        url = QUrl("https://www.163.com")
        view = HtmlView(self)
        view.load(url)
        ix = self.addTab(view, "加载中 ...")
        self.resize(800, 600)
        
        # 添加关闭按钮
        closeButton = QPushButton("关闭网页", self)
        closeButton.clicked.connect(self.closeCurrentTab)
        self.setCornerWidget(closeButton)
        
    # 关闭当前标签页
    def closeCurrentTab(self):
        ix = self.currentIndex()
        if ix >= 0:
            view = self.widget(ix)
            self.removeTab(ix)
            view.deleteLater()
        

class HtmlView(QWebEngineView):
    def __init__(self, *args, **kwargs):
        QWebEngineView.__init__(self, *args, **kwargs)
        self.tab = self.parent()

    def createWindow(self, windowType):
        if windowType == QWebEnginePage.WebBrowserTab:
            webView = HtmlView(self.tab)
            ix = self.tab.addTab(webView, "加载中 ...")
            self.tab.setCurrentIndex(ix)
            return webView
        return QWebEngineView.createWindow(self, windowType)

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    main = TabWidget()
    main.show()
    sys.exit(app.exec_())

在上面的代码中，我们添加了一个按钮 `closeButton`，并将其设置为窗口的角落部件，这样它就会出现在标签页的右上角。当用户点击按钮时，它会触发 `closeCurrentTab` 槽函数，该函数会关闭当前标签页，并删除对应的 `HtmlView` 对象。
