编辑：由于无法回答，我将问题分为简单和复杂两部分，以便更清楚地说明问题所涉及的内容。
简单问题：
对于以下 MWE，有没有办法清除附录第一页的页眉，但保留水平标尺和页码（就像第 1 章的第一页一样）？
\documentclass[12pt, openright, twoside, a4paper, chapter=TITLE, english]{memoir}

\usepackage{titlesec}
\titleformat{\chapter}{\normalfont\normalsize\scshape\bfseries}{\thechapter}{1em}{}

\pagestyle{fancy}
\fancyhf{} %... clears all headers and footers
\fancyhead[LE, RO]{\thepage} %... left-even right-odd page numbering
\fancyhead[LO]{\rightmark} %... left-odd page section title
\fancyhead[RE]{\leftmark} %... right-even page subsection title
\renewcommand{\headrulewidth}{0.4pt}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%-> Create counter for appendix

\end{document}
复杂问题：
这仅仅是一个由内置的暗示性使用所激发的附录\appedix。
我避免这样做的原因\appendix是我需要一个具有不同水平级别的表格来显示章节和附录。尝试执行此操作的完整代码如下：
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%-------- STANDARD POS-TEXTUAL ELEMENTS ---------%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%-> Create counter for appendix
\newcounter{appendix}
\newcounter{appsection}[appendix]
\newcounter{appsubsection}[appsection]
%-> Change numbering format to capitalized alphabetic
\renewcommand{\theappendix}{\Alph{appendix}}
%-> Create the command to start pos-text
\def\startpostext{%
%-> Format title font and positioning
\titleformat{\chapter}{\normalfont\normalsize\scshape\bfseries}{APPENDIX \thechapter\ -- }{0em}{}
}
%-> Create appendix title command
\newcommand{\Appendix}[1]{%
%... make sure an odd blank page will be created for the Bibliography environment
\cleardoublepage
%... make sure the \leftmark and the \rightmark will be printed correctly
% \phantomsection
%... increase appendix counter
\refstepcounter{appendix}
%... mannualy add the appendix to the ToC
\addcontentsline{toc}{chapter}{\protect\numberline{}\textbf{APPENDIX \theappendix\ -- #1}}
%... make sure the appendix pages will be fancy
\fancyhf{}
\fancyhead[LE, RO]{\thepage} %... left-even right-odd page numbering
\fancyhead[RE]{APPENDIX \theappendix.\hspace{1em}\uppercase{#1}}
\fancyhead[LO]{\theappendix.\theappsection.\hspace{1em}\MakeUppercase{\appsecname}}
%-> Format title font and positioning
\rule{0cm}{0cm}\bigskip\vspace{3em}
\noindent
{\scshape\textbf{APPENDIX \theappendix\ -- #1}}
\thispagestyle{empty}
\bigskip\vspace{3em}
}
%-> Create appendix section command
\newcommand{\appsec}[1]{%
\def\appsecname{#1}
\refstepcounter{appsection}
\bigskip
\noindent
{\scshape\textbf{\theappendix.\theappsection\hspace{1em}#1}}
\bigskip
}
%-> Create appendix subsection command
\newcommand{\appsubsec}[1]{%
\refstepcounter{appsubsection}
\bigskip
\noindent
{\scshape\textbf{\theappendix.\theappsection.\theappsubsection\hspace{1em} #1}}
\bigskip
}
请注意，此处\addcontentsline{toc}{chapter}{\protect\numberline{}\textbf{APPENDIX \theappendix\ -- #1}}将附录添加到目录中，并在章节前面添加所需的缩进（水平）。此外，它还APPENDIX A -- Appendix title在目录中进行了标记。
概括：
如果有一种方法\appendix可以让我改变它们的水平并在 ToC 中显示，那就很好了。
如果有办法使用\Appendix这里介绍的定义并清除页眉（水平标尺和页码除外），那也是可以的！

你所说的“回答失败”实际上是“未能一次性指定所有要求”。
无论如何——让我们通过回忆录来发明我们自己的轮子：;-)
