在表格行中添加更多垂直空间

Question

我有这张桌子，但我需要在行中留出更多的垂直空间来容纳分数，它们非常紧密。

 \begin{tabular}{| c | c |}
 \hline
 \rowcolor{green} $x$ & $g(x)$ \\ \hline
 $0$ &  \\ \hline
$3$ &  \\ \hline
$-2$ &  \\ \hline
$\dfrac{3}{4}$ &  \\ \hline
 $\dfrac{-1}{2}$ &  \\ \hline
 & $0$ \\ \hline
 & $5$ \\ \hline
 & $-3$ \\ \hline
\end{tabular} 

Answer 1

@clara 答案的变体，其中单元格内容周围的垂直空间增加了 5pt 并重新组织了表格序言：

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabularray}

\begin{document}
\begin{tblr}{hlines, vlines,
             colspec = {*{2}{Q[c,wd=2em, mode=dmath]}}, % <--- changed
             row{1}  = {bg=green},
             rowsep  = 5pt                              % <--- added
             }
x            & g(x) \\
0            &      \\
3            &      \\
-2           &      \\
\frac{3}{4}  &      \\
\frac{-1}{2} &      \\
             & 0    \\
             & 5    \\
             & -3   \\
\end{tblr}
\end{document}

Answer 2

更新：使用dmath模式。

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabularray}
\begin{document}
\begin{tblr}
{
colspec = {Q[c,m]Q[c,m]},
hlines,vlines,
row{1}  = {bg=green},
cells   = {mode=dmath},
}
x            & g(x) \\
0            &      \\
3            &      \\
-2           &      \\
\frac{3}{4}  &      \\
\frac{-1}{2} &      \\
             & 0    \\
             & 5    \\
             & -3   \\
\end{tblr}
\end{document}

与。{NiceTabular}​nicematrix

\documentclass{article}
\usepackage{nicematrix}

\begin{document}

\begin{NiceTabular}{cc}[hvlines,colortbl-like,cell-space-limits=3pt]
\rowcolor{green} $x$ & $g(x)$ \\ 
 $0$ &  \\ 
$3$ &  \\ 
$-2$ &  \\ 
$\dfrac{3}{4}$ &  \\ 
 $\dfrac{-1}{2}$ &  \\ 
 & $0$ \\ 
 & $5$ \\ 
 & $-3$ \\
\end{NiceTabular} 

\end{document}

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage{colortbl}

\begin{document}
 {\renewcommand{\arraystretch}{2.5}\begin{tabular}{| c | c |}
 \hline
 \rowcolor{green} $x$ & $g(x)$ \\ \hline
 $0$ &  \\ \hline
$3$ &  \\ \hline
$-2$ &  \\ \hline
$\dfrac{3}{4}$ &  \\ \hline
 $-\dfrac{1}{2}$ &  \\ \hline
 & $0$ \\ \hline
 & $5$ \\ \hline
 & $-3$ \\ \hline
\end{tabular}}
