目录中的附录标签

我正在使用该类book，并且有几个附录。这些附录的标题为“附录 A”、“附录 B”等，实际上所有字母都是小写字母。为了使标签 (A、B、...) 变为小写字母，我使用了\renewcommand{\thechapter}{{\normalfont\scshape \alph{chapter}}}。虽然这样做效果很好，但它也会将目录中的附录标签更改为小写字母，而这并不是我想要的。我不知道如何避免这种情况。有没有人知道一个包或一个技巧，可以让标签 A、B 等在目录中显示为正常大写字母？

以下重现了该问题：

对于您的示例，一个足够的解决方案是在 \tableofcontents 之前重新定义 \textsc（同时确保整体被分组，因此重新定义仍然是本地的）：

{\renewcommand{\textsc}[1]{\MakeUppercase #1}
\tableofcontents
}

当目录中需要使用小型大写字母时，就需要采用一些更加精细的方法。
