Is there a setting I can input to the array
environment, which will slightly increase the horizontal spacing between each entry?
I would appreciate it if you could test your code on the following example I am using:
\documentclass{article}
\usepackage{forloop}
\newcounter{loopcntr}
\newcommand{\rpt}[2][1]{% repeat text
\forloop{loopcntr}{0}{\value{loopcntr}<#1}{#2} }
\begin{document}
\[ \begin{array}{*{5}{c}}
1 & 2 & 3 & 4 & \ldots \\
\rpt[4]{\downarrow &} \unskip \downarrow \\
x_{1}^1 & x_{1}^2 & x_{2}^1 & x_{1}^3 & \ldots \\
\end{array} \]
\end{document}
I want slightly more whitespace between each number, between each arrow, and between each x.
Best Answer
add something like
before the array.
