仅在表环境中重新定义 cite 命令

Question

我正在使用 natbib 包对论文报告进行引用：

\usepackage[authoryear,sort,round]{natbib}
\bibliographystyle{apa}

引用应该是作者年份，文中带括号，并且排序，这对我来说非常完美。

问题是，我的表格环境中的列非常大，包含大量引用。即使我使用自定义列，在表格中保留作者年份样式也很难用文本宽度来排列表格宽度。

%ltxtable configuration
\newcolumntype{L}{>{\RaggedRight\arraybackslash}X} % flush-left, while allowing hyphenation
\newcolumntype{C}{>{\Centering\arraybackslash}X} % centered, while allowing hyphenation
\newcolumntype{P}[1]{>{\RaggedRight\arraybackslash}p{#1}}

我需要重新定义 cite 命令，使其使用括号编号，而不是仅在表格环境中使用作者样式。此外，我希望括号为上标，我已经找到了解决方案，但它始终是作者年份样式：

\usepackage{letltxmacro}

\LetLtxMacro{\originalcite}{\cite}
\def\tablecite#1#{%
  \def\pretablecite{#1}%
  \tableciteaux}
\def\tableciteaux#1{%
  \textsuperscript{\expandafter\originalcite\pretablecite{#1}}%
}
\AtBeginEnvironment{table}{\let\cite\tablecite}

这是我的文档（所需的最少代码）的样子：

\documentclass[12pt,fleqn,a4paper]{book} % Default font size and left-justified equations

\usepackage{etoolbox}

% Bibliography
\usepackage[authoryear,sort,round]{natbib}
\bibliographystyle{apa}%this one order the list of references whereas abbrvnat is the elsevier thing;

\usepackage{afterpage}
\usepackage{capt-of}% or use the larger `caption` package
\usepackage{textcomp} % display ' apostrophe
\usepackage{dirtytalk} % access \say
\usepackage{longtable} %access longtable
\usepackage{lscape} %access landscape
\usepackage{pdflscape} % To rotate the page when using landscape & longtable
\usepackage{multirow} %access multirow
\usepackage{booktabs} %access \toprule & \bottomrule \cmidrule
\usepackage{changepage}%adjustwidth
\usepackage{ragged2e} % access \justify 
\usepackage{tabularx,ltxtable}
\usepackage{array}

%ltxtable configuration
\newcolumntype{L}{>{\RaggedRight\arraybackslash}X} % flush-left, while allowing hyphenation
\newcolumntype{C}{>{\Centering\arraybackslash}X} % centered, while allowing hyphenation
\newcolumntype{P}[1]{>{\RaggedRight\arraybackslash}p{#1}}

%To change the citation in the table environment 
\usepackage{letltxmacro}

\LetLtxMacro{\originalcite}{\cite}
\def\tablecite#1#{%
  \def\pretablecite{#1}%
  \tableciteaux}
\def\tableciteaux#1{%
  \textsuperscript{\expandafter\originalcite\pretablecite{#1}}%
}
\AtBeginEnvironment{table}{\let\cite\tablecite}
