将文档适配为 tglat2e 样式及其与 amsthm 和 caption 的冲突

Question

我正在尝试使我的文档tglat2e适应本期刊。请看一下这个 MWE：

\documentclass{tglat2e}

\let\proof\relax
\let\endproof\relax
%This trick is due to David Carlisle's answer to question number 43835. It fixes some issues.
\usepackage{amsthm}
\usepackage{caption}

\theoremstyle{plain}
\newtheorem{theorem}{Theorem}[section]
\newtheorem{lemma}[theorem]{Lemma}

\theoremstyle{definition}
\newtheorem{definition}[theorem]{Definition}
\newtheorem{example}[theorem]{Example}

\theoremstyle{remark}
\newtheorem{remark}[theorem]{Remark}

\begin{document}

\section{Introduction}

\begin{proof}
Proof.

\begin{proof}[Proof of Lemma]
\[
E=mc^2\qedhere
\]
%The \qedhere command does not work at all.
\end{proof}

The qed appears because it is called. With the fix, it appears now twice.\qed
\end{proof}

\begin{proof}

Here is a proof. But the qed-symbol does not occur automatically.
\end{proof}

\begin{table}[ht]
    \centering
    \caption{This is a caption which\\
    goes over two lines.}
\end{table}

\end{document}

• 本文档编译后会抛出四个错误和一个警告。这些错误都与似乎与期刊风格相冲突的呈现有关amsthm。显而易见的建议是：不要加载amsthm！但这会在我的原始文档中产生大约 500 个错误和警告。我该如何摆脱这些错误？

• 该警告与 -package 有关caption。我只需要此包来处理示例中的带换行符的标题。我该如何实现此效果？

• 此问题已修复。此修复还解决了第一项中的一个错误。证明环境不像我习惯的那样工作。它不会自动生成 qed 符号，而只会在调用一次后生成。此外，它\qedhere根本不起作用。

如果你能帮助我，我会非常高兴。谢谢！

其余错误和警告如下，供您参考：

Answer 1

包含tglat2e.cls了的大部分内容amsthm.sty，但删除了对 QED 符号的任何引用。

恢复起来并不难，只要粘贴相关的宏就可以了。

你不能使用该caption包，也不能手动将标题分成两行，除非其中一行的长度超过\@maxcaptionwd。

\caption[This is a caption]{\makebox[\csname @maxcaptionwd\endcsname][l]{This is a caption which}\\
          goes over two lines.}

可选参数显然是必要的。
