表格中的水平和垂直對齊

Question

我將建立一個具有中心對齊方式（水平和垂直）的表格。我用“規則”來實現它。不幸的是，第一欄對此沒有反應。

我的程式碼：

\documentclass[hyperref={pdfpagelabels=false}]{beamer}
% Die Hyperref Option hyperref={pdfpagelabels=false} verhindert die Warnung: Package hyperref Warning: Option `pdfpagelabels' is turned off (hyperref) because \thepage is undefined. Hyperref stopped early

這是我的問題的圖片：

Answer 1

您可以使用makecell和collcell：

\documentclass{article}
\usepackage{array,makecell,collcell}

\newcolumntype{C}{>{\collectcell\CELL}c<{\endcollectcell}}

\begin{document}

\begin{center}
\makegapedcells\setcellgapes{5pt}
\newcommand\CELL[1]{\makebox[1cm]{#1}}
\begin{tabular}{|*{5}{C|}}
\hline
$z_i$    & $-\frac{130}{81}$    & $-\frac{10}{27}$   &
  $\frac{70}{81}$   & $\frac{170}{81}$   \\\hline
$f(z_i)$ & $0{,}2$ & $0{,}4$ & $0{,}3$ & $0{,}1$  \\\hline
\end{tabular}
\end{center}

\end{document}

該\CELL命令應在使用表之前取得定義。如果所有單元格共用長度，則可以將定義放在序言中；\renewcommand當然，您可以在本地使用。

Answer 2

我不認為使用rules 是一個乾淨的解決方案，您可以透過發出例如 來增加行的高度\renewcommand{\arraystretch}{1.2}。我只包含了程式碼的相關部分，因為您的大部分程式碼似乎與問題無關。

\documentclass[hyperref={pdfpagelabels=false}]{beamer}
\usefonttheme{professionalfonts} % default family is serif
\usepackage{array,lmodern}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}
\begin{document}

\begin{frame}
\renewcommand{\arraystretch}{1.2}
\begin{tabular}{|*{5}{C{1cm}|}}\hline
$z_i^{}$ & $-\frac{130}{81}$ & $-\frac{10}{27}$ & $\frac{70}{81}$  & $\frac{170}{81}$ \\ \hline
$f(z_i)$ & $0,2$ & $0,4$ & $0,3$ & $0,1$ \\ \hline
\end{tabular}
\end{frame}

\end{document}
