我怎样才能改变这个表格样式：
% !TeX spellcheck = de_DE

像这样的表格样式吗？
答案1
\documentclass[a4paper,12pt]{article}
\usepackage[table]{xcolor}
\begin{document}
\begin{tabular}{|*{4}{c|}}
\hline
\rowcolor{yellow}
a & b & c & d \\
\hline
1 & 2 & 3 & 4 \\
\hline
\end{tabular}
\end{document}
对我来说，这不是一个很好的桌子...请考虑我上面的评论。
答案2
以下两个表格中上面的表格可能接近您的第二张截图所要求的表格。但是，我建议您优先选择下面的表格，它故意没有彩色标题、没有垂直线，水平线较少但间距适当。
\documentclass{article}
\usepackage{array,booktabs,siunitx}
\newcolumntype{Q}[1]{>{\hfil$}p{#1}<{$\hfill}} % centered, automatic math mode
\usepackage[table]{xcolor} % for "\rowcolor" macro
\begin{document}
\begin{center}
\setlength{\extrarowheight}{2pt} % for a more "open" look
\begin{tabular}{|*{5}{Q{1cm}|}} % or: {|*{b}{c|}}
\hline
\rowcolor{yellow} a & b & a+b & a-b & b-a\\
\hline
2 & 3 & 5 & -1 & 1\\
\hline
4 & -2 & 2 & 6 & -6\\
\hline
3 & -5 & -2 & 8 & -8\\
\hline
\end{tabular}
\bigskip
\setlength{\extrarowheight}{0pt} % don't need this extra parameter anymore
\begin{tabular}{@{}S[table-format=1.0]*{4}{S[table-format=-1.0]}@{}}
\toprule
{$a$} & {$b$} & {$a+b$} & {$a-b$} & {$b-a$}\\
\midrule
2 & 3 & 5 & -1 & 1\\
4 & -2 & 2 & 6 & -6\\
3 & -5 & -2 & 8 & -8\\
\bottomrule
\end{tabular}
\end{center}
\end{document}
