How to change the rules (line) color of a table in LaTeX?

In this tutorial, you will learn how to change the color of lines or rules of a table in LaTeX.

To set the line color of a table in LaTeX, you can use the xcolor package with the [table] option. Like \usepackage[table]{xcolor}, then you can use the \arrayrulecolor{<color>} command before tabular.

Also, you can do a similar thing with the colortbl package.

\documentclass{article}
\usepackage[table]{xcolor}
% \usepackage{colortbl} % Or use this package

\begin{document}

\begin{table}[h]
\centering
\arrayrulecolor{red} % Change color of table lines (rules)
\begin{tabular}{|c|c|c|}
\hline
Column 1 & Column 2 & Column 3 \\
\hline
Text & Text & Text \\
\hline
Text & Text & Text \\
\hline
Text & Text & Text \\
\hline
\end{tabular}
\caption{Colored lines of a Table}
\end{table}

\begin{table}[h]
\centering
\arrayrulecolor{blue} % Change color of table lines (rules)
\begin{tabular}{|c|c|c|}
\hline
Column 1 & Column 2 & Column 3 \\
\hline
Text & Text & Text \\
\hline
Text & Text & Text \\
\hline
Text & Text & Text \\
\hline
\end{tabular}
\caption{Colored lines of a Table}
\end{table}

\end{document}

Output:

Specific color for specific line in the table

If you want to add a specific color for a specific line then you can use the \arrayrulecolor{<color>} command with the specific \hline. And for vertical lines, you have to use !{\color{<color-name>}\vrule}, when we set the column alignment of the table.

\documentclass{article}
\usepackage[table]{xcolor}
% \usepackage{colortbl} % Or use this package

\begin{document}

\begin{table}[h]
\centering
\begin{tabular}{!{\color{blue}\vrule}c!{\color{green}\vrule}c!{\color{lime}\vrule}}
\hline
Column 1 & Column 2 \\
\arrayrulecolor{yellow}\hline
Text & Text \\
\arrayrulecolor{red}\hline
Text & Text \\
\arrayrulecolor{brown}\hline
Text & Text \\
\hline
\end{tabular}
\caption{Colored lines of a Table}
\end{table}

\end{document}

Output:

Change line color with tabu package

You can also use the tabu package to set color of the lines of a table. This package provides a tabu environment to make tables and \taburulecolor{<color>} command to set color of lines.

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabu}
\begin{document}

\taburulecolor{green!30!black}
\begin{tabu}{|c|c|c|}
    \hline
    Column 1 & Column 2 & Column 3 \\
    \hline
    Text & Text & Text \\
    \hline
    Text & Text & Text \\
    \hline
    Text & Text & Text \\
    \hline
\end{tabu}

\end{document}

Output:
