I am trying to create a matrix in texmaker when using the wizard-->quick tabular i get a table, but I want to have equal spacing between the columns , so at the option i choose fixed column width when i see the code I noticed that
%\usepackage{array} is required
so i place it the pre-amble and hit compile but it doesnot allow me to compile it and goes into a never ending loop
\documentclass[authoryear,preprint,review,12pt]{elsarticle}
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{mathtools}
\begin{document}
\begin{tabular}{|c|c|c|c|c|}
\hline
• & \multicolumn{4}{c|}{location} \\
\hline
• & 1 & 2 & 3 & 4 \\
\hline
Average & • & • & • & • \\
\hline
Average measure& • & • & • & • \\
\hline
A & • & • & • & • \\
\hline
B & • & • & • & • \\
\hline
C & • & • & • & • \\
\hline
D & • & • & • & • \\
\hline
E & • & • & • & • \\
\hline
\end{tabular}
\end{document}
Is there a way to set a designated width to the code used above, with out the use of packages ?
