我正在使用 natbib 套件引用論文報告：
\usepackage[authoryear,sort,round]{natbib}
\bibliographystyle{apa}
引文應該是作者年份，並在文本中加上括號，並且還進行了排序，這對我來說非常適合。
問題是我的表格環境中有非常大的列，其中包含大量引用。即使我使用自訂列，將 auhtoryear 樣式保留在表格內也會導致很難用 textwidth 排列表格寬度。
%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}}
我需要重新定義 cite 指令，使其用括號編號，而不是僅在表格環境內使用作者樣式。另外，我希望括號是上標，我已經找到了解決方案，但它始終採用authoryear風格：
\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}
這是我的文檔（最小=所需的程式碼）的樣子：
\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
