Bold part of column in table

Question

i want to do table, where i indicate the best results of tests. To do it i have to bold properly rows and columns. With

\Xcline{2-5}{2pt}

i can bold rows, but how can i do the same thing with columns?

Code which i use to draw table:

\begin{table}[ht!]
\begin{center}
\begin{tabular}{|c|c|c|c|c|}
\hline
\diagbox{board}{tag} & tag1 & tag2 & tag3 &  tag4 \\ \hline
 \multirow{3}{*}{board1} & qr & dm & ar & ap \\ \cline{2-5} &
 qr  & dm & ar & ap \\ \cline{2-5} &
 qr  & dm & ar & ap \\ \cline{2-5} \hline
 \multirow{3}{*}{board2} & qr  & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} \hline\Xcline{2-5}{1.5pt}
  \multirow{3}{*}{board3} & qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} \hline \Xcline{2-5}{1.5pt}
\end{tabular}
\caption{Table_caption}
\end{center}
\end{table}

There are (at least) two ways to highlight the contents of cells -- to use a bold font face for the contents, and to cast the entire cell in a color or shade of gray. Which method of emphasis are you trying to implement? — Mico, Jul 25 '19 at 11:31

I propose this solution, which relies on the boldline package (shipunov bundle), which defines lines of variable thickness for tables, both horizontal and vertical. It uses as an argument a number which represents the multiple of default line thickness. In the following code, I used 5, which means a thickness of 2pt:

\documentclass[12pt,fleqn]{article}
\usepackage{pict2e}
\usepackage{keyval}
\usepackage{calc}
\usepackage{fp}
\usepackage{diagbox}
\usepackage{booktabs}
\usepackage{tabularx,colortbl, makecell, caption, multirow}
\usepackage{boldline} 

\begin{document}

\begin{table}[htb!]
\centering
\begin{tabular}{|c|c|c|c|c|}
\hline
\diagbox{board}{tag} & tag1 & tag2 & tag3 & tag4 \\ \hline
 \multirow{3}{*}{board1} & qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} \hline
 \multirow{3}{*}{board2} & qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} &
 qr & dm & ar & ap \\ \cline{2-5} \hline\clineB{2-5}{5}
\multirow{3}{*}{board3}& \multicolumn{1}{V{5}c|}{qr} & dm & ar & \multicolumn{1}{|cV{5}}{ap} \\ \cline{2-5}
 &\multicolumn{1}{V{5}c|}{qr} & dm & ar & \multicolumn{1}{|cV{5}}{ap} \\ \cline{2-5}
 &\multicolumn{1}{V{5}c|}{qr} & dm & ar & \multicolumn{1}{|cV{5}}{ap} \\[2pt] %
\hline
\noalign{\vskip-2.4pt}\clineB{2-5}{5}
\end{tabular}
\caption{Table caption}
\end{table}

\end{document}

Thank you, it works fine – Filip Jarecki Jul 25 '19 at 12:29 — Filip Jarecki, Jul 25 '19 at 12:29

Here is a way to do that table with {NiceTabular} of nicematrix.

In {NiceTabular}, you merge cells vertically and horizontally with the command \Block. You can ``draw'' around the block with the key draw.
The key hvlines draws all the rules excepted in the blocks (but if the key transparent is used for the blocks, the rules are drawn).
{NiceTabular} has a built-in command \diagbox (however, that command doesn't set the size of the cell and that's why I have put a \rule).

However, you need several compilations.

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\begin{table}[ht!]
\centering
\begin{NiceTabular}{wc{1.3cm}cccc}[hvlines]
\rule[-8pt]{0pt}{20pt}
\diagbox{board}{tag} & tag1 & tag2 & tag3 &  tag4 \ 
\Block{3-1}{board1} & qr & dm & ar & ap \

&  qr  & dm & ar & ap \

&  qr  & dm & ar & ap \ 
\Block{3-1}{board2} & qr  & dm & ar & ap \ 
& qr & dm & ar & ap \ 
& qr & dm & ar & ap \ 
\Block{3-1}{board3} & 
\Block[transparent,draw,line-width=2pt]{3-4}{} qr & dm & ar & ap \ 
& qr & dm & ar & ap \ 
& qr & dm & ar & ap 
\end{NiceTabular}
\caption{Table caption}
\end{table}
\end{document}

If you want the bold line within the block, it's also possible but it's a little more complicated (and you have to load Tikz).

\documentclass{article}
\usepackage{nicematrix}
\usepackage{tikz}
\begin{document}
\begin{table}[ht!]
\centering
\begin{NiceTabular}{wc{1.3cm}cccc}[hvlines]
\rule[-8pt]{0pt}{20pt}
\diagbox{board}{tag} & tag1 & tag2 & tag3 &  tag4 \ 
\Block{3-1}{board1} & qr & dm & ar & ap \

&  qr  & dm & ar & ap \

&  qr  & dm & ar & ap \ 
\Block{3-1}{board2} & qr  & dm & ar & ap \ 
& qr & dm & ar & ap \ 
& qr & dm & ar & ap \ 
\Block{3-1}{board3} & 
\Block[transparent,tikz={clip},tikz={draw,line width=2pt}]{3-4}{} qr & dm & ar & ap \ 
& qr & dm & ar & ap \ 
& qr & dm & ar & ap 
\end{NiceTabular}
\caption{Table caption}
\end{table}
\end{document}
