How can I create a table with empty corner and continous vertical lines like this?

enter image description here

Here is what I have so far:

enter image description here

\documentclass[journal]{IEEEtran}
\usepackage{mathtools}
\usepackage{booktabs}

\begin{document}
  \begin{table}[!t]
  \centering
  \caption{Adjacency Matrix}
  \label{tab:Adjacency Matrix}
  \begin{tabular}{|c|c|c|c|c|c|}
  \toprule
$V_1$ & $V_2$ & $V_3$ & $V_4$ & $V_5$ \
\midrule
$V_1$ \
\midrule
$V_2$ \
\midrule
$V_3$ \
\midrule
$V_4$ \
\midrule
$V_5$ \
\bottomrule
\end{tabular}
\end{table}
\end{document}

Also please suggest if you have a nice idea to do it.

I would suggest to use tabularray for this kind of tables or NiceMatrix but I am not familiar with the latter, so I give a solution based on tabularray

enter image description here

\documentclass[journal]{IEEEtran}
\usepackage{mathtools}
\usepackage{tabularray}
    \UseTblrLibrary{booktabs}

\begin{document}
  \begin{table}[!t]
    \centering
    \caption{Adjacency Matrix}
    \label{tab:Adjacency Matrix}
    \begin{tblr}{
            colspec={*6{c}},
            vline{1} = {2-Z}{0.8pt},
            vline{2,Z} = {0.8pt},
            vline{3-Y} = {0.3pt},
            hline{1} = {2-Z}{0.8pt},
            hline{2,Z} = {0.8pt},
            hline{3-Y} = {0.3pt},
            row{1} = {mode=math},
            column{1} = {mode=math},
        }
        & V_1 & V_2 & V_3 & V_4 & V_5 \
        V_1 & 1 & 1 & 0 & 0 & 1 \
        V_2 & 1 & 0 & 1 & 0 & 1 \
        V_3 & 0 & 1 & 0 & 1 & 0 \
        V_4 & 0 & 0 & 1 & 0 & 1 \
        V_5 & 1 & 1 & 0 & 1 & 0 \
    \end{tblr}
  \end{table}
\end{document}

  • It looks very nice but somehow I got a lot of errors in Overleaf. Also how would you fix the width size for every columns and rows? https://ibb.co/g7kTy0T – emnha Aug 18 '22 at 16:11
  • I am afraid Overleaf is still not up-to-date and tabularray is still not available. However, you can download the zip-file, extracts the tabularray.sty and upload it in your project on Overleaf. Then it will work. – Celdor Aug 18 '22 at 16:16
  • You're right. It works now. How would you fix the width size of columns and rows? – emnha Aug 18 '22 at 16:18
  • It's a typo in my code. Change 5 to 6 in colspec={*5{c}}, ... and it will work – Celdor Aug 18 '22 at 16:23
  • It still works but for now the width of columns and rows fits the content. I want to make them fixed instead. – emnha Aug 18 '22 at 16:49
  • This is done in colspec, e.g. colspec={Q[4em,c] *5{Q[2.5em,c]}}. Expand *5 to individual column spec. if you need every one of them to have an individual width. Besides c is equivalent to Q[c], which is used by tabularray in case you want even more tunings. – Celdor Aug 18 '22 at 17:00
  • If I add two more columns like the first row & V_1 & V_2 & V_3 & V_4 & V_5 & V_6 & V_7\\ then I get a warning like this from Overleaf: "Package tabularray Warning: Table width is too small, need 12.20003pt more!". Do you have any idea to remove this warning? – emnha Aug 18 '22 at 20:32
  • It's because the document class IEEEtran sets two column layout and if your table doesn't fit a column width you get a warning. You have to reduce the table width somehow or enclose it within table* (starred) instead of regular table environment. – Celdor Aug 18 '22 at 21:29
  • The table will no longer flow with text and will be placed at the top of the next page but will span two columns and fit the whole page width. – Celdor Aug 18 '22 at 21:31
  • Thanks, I solved it by reducing the column's width. – emnha Aug 18 '22 at 22:25

It's easy with the environment {NiceTabular} of nicematrix.

\documentclass{article}
\usepackage{nicematrix}

\begin{document}


\renewcommand{\arraystretch}{1.2}
\begin{NiceTabular}{>{\bfseries}cccccc}[hvlines,corners=NW] % NW = north west 
\RowStyle{\bfseries}
  & 1 & 2 & 3 & 4 & 5 \
1 &   &   & 1 & 1 &   \
2 &   &   &   & 1 & 1 \
3 & 1 &   &   &   & 1 \
4 & 1 & 1 &   &   &   \
5 &   & 1 & 1 &   &   \
\end{NiceTabular}


\end{document}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).

Answer to the comment. Usually, one uses the rules of \booktabs (\toprule, midrule, \bottomrule, etc.) only with a design without any vertical rule...

However, if you want to add rules with the thickness of a \toprule of booktabs (equal to \heavyrulewidth), it's possible with nicematrix by defining a custom style of line with the key custom-line:


\documentclass{article}
\usepackage{nicematrix,booktabs,tikz}

\begin{document}


\NiceMatrixOptions
  {
    custom-line = 
     {
       command = boldhline ,
       ccommand = cboldhline ,
       tikz = { line width = \heavyrulewidth } , 
       total-width = \heavyrulewidth 
     }
  }


\renewcommand{\arraystretch}{1.2}
\begin{NiceTabular}{>{\bfseries}cccccc}[hvlines,corners=NW] % NW = north west 
\cboldhline{2-last}
\RowStyle{\bfseries}
  & 1 & 2 & 3 & 4 & 5 \
1 &   &   & 1 & 1 &   \
2 &   &   &   & 1 & 1 \
3 & 1 &   &   &   & 1 \
4 & 1 & 1 &   &   &   \
5 &   & 1 & 1 &   &   \
\boldhline
\end{NiceTabular}


\end{document}
