I want to increase the line spacing in the following array table, what should I do?

\documentclass{article}
\usepackage{amsmath, amssymb}
\begin{document}
$\begin{array} {|c|c|c|c|} \hline X & 1 & 2 & 3 \\ \hline \mathrm{p}(X=x_{i}) & \dfrac{1}{22} & \dfrac{9}{22} & \dfrac{6}{11} \\ \hline \end{array}$
\end{document}

• Do you want to increase the line spacing per se, or do you mainly want to get some visual separation between the cell contents and the horizontal rules? Please advise.

A possible solution is to use the tabularray package:

\documentclass{article}

\usepackage{amsmath,amssymb,tabularray}

\begin{document}

$\begin{tblr}{cells=c,rowsep=3pt,hlines,vlines} X & 1 & 2 & 3 \\ \operatorname{p}(X=x_{i}) & \dfrac{1}{22} & \dfrac{9}{22} & \dfrac{6}{11} \\ \end{tblr}$

\end{document}


With {NiceArray} of nicematrix, you have an option cell-space-limits to set a minimal space above and below each cell. Moreover, the key hvlines draws all the rules.

\documentclass{article}
\usepackage{nicematrix}

\begin{document}

$\begin{NiceArray}{cccc}[hvlines,cell-space-limits=3pt] X & 1 & 2 & 3 \\ \mathrm{p}(X=x_{i}) & \dfrac{1}{22} & \dfrac{9}{22} & \dfrac{6}{11} \\ \end{NiceArray}$

\end{document}

Using cellspace package with \setlength.

\documentclass{article}
\usepackage{amsmath, amssymb}
\usepackage{array} % for tabular environment
\usepackage{cellspace} % for adjusting cell spacing

% Set minimum vertical spacing above and below cells in the "S" columns
\setlength\cellspacetoplimit{3pt}
\setlength\cellspacebottomlimit{3pt}

\begin{document}

$\begin{array}{|Sc|Sc|Sc|Sc|} \hline X & 1 & 2 & 3 \\ \hline \mathrm{p}(X=x_{i}) & \dfrac{1}{22} & \dfrac{9}{22} & \dfrac{6}{11} \\ \hline \end{array}$

\end{document}
