# Editing a table

I want to edit the table to the left below, into the second screenshot to the right (the three tiny short lines indicate that this line should not be there, the 'Test' below should not be there too).

\documentclass[border=1cm]{standalone}

\begin{document}

\begin{tabular}{|c||c|c|c|c|c|}\hline
\textbf{Test} & 1 & 2 & 3 & 4 & 5  \\ \hline
{\textbf{U}} \\ \hline
{a} & 1 & 0 & 0 & 0 & 0 \\ \hline
{b} & 0 & 1 & 0 & 0 & 0 \\ \hline
{c} & 0 & 0 & 1 & 0 & 0 \\ \hline
{d} & 0 & 0 & 0 & 1 & 0 \\ \hline
{\textbf{W}}\\ \hline
{e} & \textbf{1} & 0 & 0 & 0 & 0  \\ \hline
{f} & 0 & \textbf{1} & \textbf{1} & \textbf{1} & 0 \\ \hline
{g} & 0 & 1 & 1 & 0 & \textbf{1} \\ \hline

\end{tabular}

\end{document}


Like this? Using \cline and some multicolumns.

\documentclass[border=1cm]{standalone}

\begin{document}

\begin{tabular}{|c||c|c|c|c|c|}\hline
& \multicolumn{5}{c|}{Test}\\\cline{2-6}
\textbf{Test} & 1 & 2 & 3 & 4 & 5  \\ \hline
\textbf{U}&\multicolumn{5}{c|}{} \\ \hline
a & 1 & 0 & 0 & 0 & 0 \\ \hline
b & 0 & 1 & 0 & 0 & 0 \\ \hline
c & 0 & 0 & 1 & 0 & 0 \\ \hline
d & 0 & 0 & 0 & 1 & 0 \\ \hline
\textbf{W}&\multicolumn{5}{c|}{}\\ \hline
e & \textbf{1} & 0 & 0 & 0 & 0  \\ \hline
f & 0 & \textbf{1} & \textbf{1} & \textbf{1} & 0 \\ \hline
g & 0 & 1 & 1 & 0 & \textbf{1} \\ \hline

\end{tabular}

\end{document}

• Yes, exactly what I was looking for! Thanks – d4rty Nov 10 '15 at 14:55
• @Mico the ones i just deleted? Or do you mean others? – Johannes_B Nov 10 '15 at 14:57

You can also do by using booktabs. This is the easiest way to present the data in tables

\documentclass[border=1cm]{standalone}

\usepackage{booktabs}

\begin{document}

\begin{tabular}{ccccccc}

\toprule
\textbf{Test} & & 1 & 2 & 3 & 4 & 5  \\ \midrule
{\textbf{U}}& & & & & \\ \midrule
& {a} & 1 & 0 & 0 & 0 & 0 \\ \midrule
& {b} & 0 & 1 & 0 & 0 & 0 \\ \midrule
& {c} & 0 & 0 & 1 & 0 & 0 \\ \midrule
& {d} & 0 & 0 & 0 & 1 & 0 \\ \midrule
{\textbf{W}}& & & & & \\ \midrule
&{e} & \textbf{1} & 0 & 0 & 0 & 0  \\ \midrule
& {f} & 0 & \textbf{1} & \textbf{1} & \textbf{1} & 0 \\ \midrule
&{g} & 0 & 1 & 1 & 0 & \textbf{1} \\ \bottomrule
\end{tabular}

\end{document}


• A couple of comments: (i) I think the word "Test" is supposed to be in the top row, spanning columns 2 thru 6. (ii) Since you're using the superior booktabs package, you may also want to show just how much better the table can look if the interior horizontal lines are omitted along with all those vertical lines. – Mico Nov 10 '15 at 17:46
