Reducing the width of table cells

Question

does anybody know if tabular has any properties where we are able to adjust the width of individual columns?

I'm specifically wanting to reduce the space around the arrows and also around the text on the left-hand side. I'm essentially trying to reduce the width of the whole thing without changing the size of the tables. I'm ideally wanting a solution that doesn't involve making any new commands and was hoping there is something simple to do this.

I also know that the way I have done my arrows is not the most efficient, but I wanted to make the arrows a little longer than what was given. So if anybody has a simple solution to this too, then that would be amazing.

Thankyou! :D

Answer 1

The TAB environment is provided by easytable package. From its documentation, in \begin{TAB}(e,0.7cm,0.7cm), the minimum x- and y-size of each cell are both set to 0.7cm.

Therefore it works to use a smaller dimension, for example 0.5cm:

\documentclass{article}
\usepackage{amsmath}
\usepackage[thinlines]{easytable}
\usepackage{adjustbox}

\begin{document}

\setlength{\tabcolsep}{3pt}

\centering
\begin{tabular}{rccccccc}
& Text && Text && Text && Text   \\[0.25cm]
\begin{tabular}{c} TextText \\ Text: \end{tabular} 
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} & \(\xrightarrow[\phantom{Spa}]{Text}\)
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} & \(\xrightarrow[\phantom{Spa}]{Text}\)
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} & \(\xrightarrow[\phantom{Spa}]{Text}\)
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} \\[1.5cm]

\begin{tabular}{c} TextText \\ Text: \end{tabular} 
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} & \(\xrightarrow[\phantom{Spa}]{Text}\)
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} & \(\xrightarrow[\phantom{Spa}]{Text}\)
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} & \(\xrightarrow[\phantom{Spa}]{Text}\)
  & \adjustbox{valign=c}{\begin{TAB}(e,0.5cm,0.5cm){|c|c|c|}{|c|c|c|}  1 &  1 &  1  \\   1 &  1 &  1  \\   1 &  1 &  1 \end{TAB}} \\[1.5cm]
\end{tabular}
\end{document}

Note that \setlength{\tabcolsep}{3pt} is used to reduce the column separation in tabular environment, which is the separation around TAB environments and/or arrows.
