我正在尝试使用 tabular 整理多列表格。由于我对 latex 不太熟悉，所以我依赖于tablesgenerator.com生成代码，即：
% Please add the following required packages to your document preamble:
% \usepackage{booktabs}
% \usepackage{multirow}
% \usepackage[table,xcdraw]{xcolor}
% If you use beamer only pass "xcolor=table" option, i.e. \documentclass[xcolor=table]{beamer}
\begin{table}[]
\begin{tabular}{@{}cc
>{\columncolor[HTML]{000000}}c
>{\columncolor[HTML]{000000}}c @{}}
\multicolumn{2}{c}{} & \multicolumn{2}{c}{\cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} Party Labels}} \\
\multicolumn{2}{c}{\multirow{-2}{*}{}} & {\color[HTML]{FFFFFF} High stability} & {\color[HTML]{FFFFFF} Low stability} \\
\cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} } & \cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} High stability} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Stable systems} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Ephemeral parties} \\
\multirow{-2}{*}{\cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} \begin{tabular}[c]{@{}c@{}}Programmatic\\ positions\end{tabular}}} & \cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} Low stability} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Empty labels} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Unstable systems}
\end{tabular}
\end{table}
得出下表：
这或多或少是我需要的，但由于某种原因，第一行最后一个单元格的单元格大小（派对标签) 比后面几行的单元格要短一些。这有点烦人，因为它破坏了表格的布局。
有什么想法可以使最后一列的单元格宽度相等吗？
谢谢！
PS：如果我使用网站建议的选项，\usepackage[table,xcdraw]{xcolor}它会抛出一个选项冲突的错误，所以我将其设置为\usepackage[table]{xcolor}。我将所有这些都与一起使用beamer。
更新 -可编译/可重现的代码：
\documentclass[xcolor=table]{beamer}
\mode<presentation> {
\usetheme{Madrid}}
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables
\usepackage{multirow}
\usepackage[table]{xcolor}
\begin{document}
\begin{frame}
\begin{table}[]
\begin{tabular}{@{}cc
>{\columncolor[HTML]{000000}}c
>{\columncolor[HTML]{000000}}c @{}}
\multicolumn{2}{c}{} & \multicolumn{2}{c}{\cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} Party Labels}} \\
\multicolumn{2}{c}{\multirow{-2}{*}{}} & {\color[HTML]{FFFFFF} High stability} & {\color[HTML]{FFFFFF} Low stability} \\
\cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} } & \cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} High stability} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Stable systems} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Ephemeral parties} \\
\multirow{-2}{*}{\cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} \begin{tabular}[c]{@{}c@{}}Programmatic\\ positions\end{tabular}}} & \cellcolor[HTML]{000000}{\color[HTML]{FFFFFF} Low stability} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Empty labels} & \cellcolor[HTML]{EFEFEF}{\color[HTML]{000000} Unstable systems}
\end{tabular}
\end{table}
\end{frame}
\end{document}
答案1
问题的原因@{}在于列定义的开始和结束。如果删除它们，那么前两行的黑色将变得相同。
但是，表格的设置方式非常复杂。我尝试清理您的代码并使用白色和黑色的标准名称：
\documentclass[xcolor=table]{beamer}
\mode<presentation> {
\usetheme{Madrid}}
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables
\usepackage{multirow}
\begin{document}
\begin{frame}
\begin{table}
\begin{tabular}{>{\color{white}}c
>{\color{white}}c
>{\columncolor{black}}c
>{\columncolor{black}}c}
\multicolumn{2}{c}{} & \multicolumn{2}{c}{\cellcolor{black}{\color{white} Party Labels}} \\
\multicolumn{2}{c}{} & \color{white} High stability & \color{white} Low stability \\
\cellcolor{black}{Programmatic} & \cellcolor{black}{High stability}
& \cellcolor{white}{Stable systems} & \cellcolor{white}{Ephemeral parties} \\
\cellcolor{black}{positions} & \cellcolor{black}{Low stability}
& \cellcolor{white}{Empty labels} & \cellcolor{white}{Unstable systems}
\end{tabular}
\end{table}
答案2
与。{NiceTabular}nicematrix
\documentclass{beamer}
\mode<presentation>{\usetheme{Madrid}}
\usepackage{nicematrix}
\begin{document}
\newcolumntype{C}{>{\columncolor{black}\color{white}}c}
\begin{frame}
\begin{NiceTabular}{CCcc}[corners,colortbl-like]
\RowStyle[nb-rows=2,rowcolor=black,color=white]{}& & \Block{1-2}{Party Labels} \\
& & High stability & Low stability \\
Programmatic & High stability & Stable systems & Ephemeral parties \\
positions & Low stability & Empty labels & Unstable systems
\end{NiceTabular}
\end{frame}
\end{document}
