问题:表格中有裂缝。我该如何修复它?
答案1
正如 @daleif 在评论中所述,\\
将始终创建新行。 您还可以使用\newline
,但对于支持多行的列,如p
、、等。 在您的例子中,您可以在左对齐列中使用。当然,您需要添加包m
。b
\makecell[l]{..}

也许你喜欢:-):
没有垂直规则,水平规则来自booktabs
包,重新排列序言:
\documentclass{beamer}
%\usetheme{Boadilla}
\usetheme{Warsaw}
\setbeamercolor{structure}{fg=cyan!90!black}
\usepackage{mathtools}% it also load "amsmath"
\usepackage{array,booktabs, makecell, tabularx}
\renewcommand\theadfont{\small\bfseries}
\renewcommand\theadgape{}
\usepackage{rotating} % graphicx is loaded by "beamer"
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing}
\begin{document}
\begin{frame}
\frametitle{My table \dots}
\centering
\setcellgapes{3pt}
\makegapedcells
\begin{tabular}{ l *{2}{>{$}c<{$}} }
\toprule
\thead{Har class Class}
& \text{\thead{XYZ (in words)}}
& \text{\thead{Truple}} \\
\midrule
General vktm
& \mathcal{O}(1) & \mathcal{O}(1) \\
It is only a text
& \mathcal{O}(1) & \mathcal{O}(1) \\
\makecell[l]{Grfingiignigijfi \\jnferf}
& \mathcal{O}(1) & \mathcal{O}(1) \\
jvjtntg
& \mathcal{O}(1) & \mathcal{O}(1) \\
frcjnrtgvtng
& \mathcal{O}(1) & \mathcal{O}(1) \\
\bottomrule
\end{tabular}
\end{frame}
\end{document}
