# Outlining specific parts of array

I couldn't find this anywhere else. I have an array with a bunch of numbers in it, and I am very new to posting on this forum.

This is from a template that I have to use for a document. Here's the code for the table. What I want is that last column to only have a box around the bottom right number. How can I do that?

\begin{table}[tbp]
$\begin{array}{c | c | c | c | c | c | } \multicolumn{1}{c}{ j } & \multicolumn{1}{c}1 & \multicolumn{1}{c}2 & \multicolumn{1}{c}4 & \multicolumn{1}{c}7 & \multicolumn{1}{c}{\text{max}} \\ \cline{2-6} 1 & 1 & 2 & 4 & 7 & 7 \\ \cline{2-6} 2 & 2 & 4 & 8 & 2 & 8 \\ \cline{2-6} 3 & 3 & 6 & 4 & 5 & 6 \\ \cline{2-6} 4 & 4 & 8 & 8 & 4 & 8 \\ \cline{2-6} 5 & 5 & 6 & 4 & 3 & 6 \\ \cline{2-6} 6 & 6 & 4 & 8 & 6 & 8 \\ \cline{2-6} 7 & 7 & 2 & 4 & 1 & 7 \\ \cline{2-6} 8 & 8 & 0 & 0 & 8 & 8 \\ \cline{2-6} \text{min} & & & & & 7 \\ \cline{6-6} \end{array}$
\end{table}

Here's the picture of whta it's generating.

• Hello, your sample doesn't compile. Please provide a minimal working example next time. :-) – frougon Apr 3 at 8:53

Here is one possibility:

\documentclass{article}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}

\begin{document}
$\begin{array}{c|c|c|c|c|c} \multicolumn{1}{c}{ j } & \multicolumn{1}{c}1 & \multicolumn{1}{c}2 & \multicolumn{1}{c}4 & \multicolumn{1}{c}7 & \multicolumn{1}{c}{\text{max}} \\ \cline{2-5} 1 & 1 & 2 & 4 & 7 & 7 \\ \cline{2-5} 2 & 2 & 4 & 8 & 2 & 8 \\ \cline{2-5} 3 & 3 & 6 & 4 & 5 & 6 \\ \cline{2-5} 4 & 4 & 8 & 8 & 4 & 8 \\ \cline{2-5} 5 & 5 & 6 & 4 & 3 & 6 \\ \cline{2-5} 6 & 6 & 4 & 8 & 6 & 8 \\ \cline{2-5} 7 & 7 & 2 & 4 & 1 & 7 \\ \cline{2-5} 8 & 8 & 0 & 0 & 8 & 8 \\ \cline{2-6} \text{min} & & & & & \multicolumn{1}{|c|}{7} \\ \cline{6-6} \end{array}$
\end{document}

Is it like the following?

\documentclass{article}
\usepackage{amsmath,array}

\begin{document}

$\begin{array}{c | c | c | c | c | c } \multicolumn{1}{c}{j} & \multicolumn{1}{c}{1} & \multicolumn{1}{c}{2} & \multicolumn{1}{c}{4} & \multicolumn{1}{c}{7} & \multicolumn{1}{c}{\max} \\ \cline{2-5} 1 & 1 & 2 & 4 & 7 & 7 \\ \cline{2-5} 2 & 2 & 4 & 8 & 2 & 8 \\ \cline{2-5} 3 & 3 & 6 & 4 & 5 & 6 \\ \cline{2-5} 4 & 4 & 8 & 8 & 4 & 8 \\ \cline{2-5} 5 & 5 & 6 & 4 & 3 & 6 \\ \cline{2-5} 6 & 6 & 4 & 8 & 6 & 8 \\ \cline{2-5} 7 & 7 & 2 & 4 & 1 & 7 \\ \cline{2-5} 8 & 8 & 0 & 0 & 8 & 8 \\ \cline{2-6} \multicolumn{1}{c}{\min} & \multicolumn{4}{c|}{} & \multicolumn{1}{c|}{7} \\ \cline{6-6} \end{array}$

\end{document}
