Square table on the right column

Question

I have a latex code here :

\documentclass{article}
\usepackage{multicol}
\usepackage{enumitem,amssymb}
\usepackage{pdfpages}
\usepackage[thinlines]{easytable}
\newlist{todolist}{itemize}{2}
\setlist[todolist]{label=$\square$}
\begin{document}
\begin{multicols}{2}
\begin{itemize}
  \item Immediate plan of action.
\begin{todolist}
    \item List item 1 goes here.
    \item List item 2 goes here.
    \begin{todolist}
      \item Sublist item 1 goes here.
      \item Sublist item 2 goes here.
    \end{todolist}
    \item List item 3 goes here
    \item List item 4 goes here.
  \end{todolist}
\end{itemize}
\columnbreak
\begin{TAB}(r,1cm,1cm)[5pt]{|cccccccccc|}{|cccccccccc|}
A & I & I & R & D & A & T & O & Y & T \ 
C & O & M & M & U & T & A & T & O & R \ 
P & S & Y & A & I & C & R & G & B & S \ 
D & R & Q & U & O & T & I & E & N & T \ 
E & O & A & A & B & E & L & I & A & N \ 
M & I & D & C & O & A & P & A & A & H \ 
I & T & U & P & R & O & D & U & C & T \ 
M & O & N & G & W & A & R & T & T & T \ 
R & T & T & A & P & I & T & O & A & T \ 
S & E & M & I & G & R & O & U & P & C \ 
\end{TAB}
\end{multicols}
\begin{multicols}{2}
\begin{itemize}
  \item 1.
\begin{todolist}
    \item List item 1 goes here.
    \item List item 2 goes here.
    \begin{todolist}
      \item Sublist item 1 goes here.
      \item Sublist item 2 goes here.
    \end{todolist}
    \item List item 3 goes here
    \item List item 4 goes here.
  \end{todolist}
\end{itemize}
\columnbreak
\begin{TAB}(r,1cm,1cm)[5pt]{|cccccccccc|}{|cccccccccc|}
A & I & I & R & D & A & T & O & Y & T \ 
C & O & M & M & U & T & A & T & O & R \ 
P & S & Y & A & I & C & R & G & B & S \ 
D & R & Q & U & O & T & I & E & N & T \ 
E & O & A & A & B & E & L & I & A & N \ 
M & I & D & C & O & A & P & A & A & H \ 
I & T & U & P & R & O & D & U & C & T \ 
M & O & N & G & W & A & R & T & T & T \ 
R & T & T & A & P & I & T & O & A & T \ 
S & E & M & I & G & R & O & U & P & C \ 
\end{TAB}
\end{multicols}
\end{document}

The column on the right does not seem to be a square. How can I make it to a square with a specific font size. How can I reduce the margin of the page?

How can I reduce the width of first column to give more space to second column?

Answer 1

Use the b option in the TAB environment, which produces "equal row heights and equal column widths" (from the documentation). This results in a more square representation of the table. You may also consider using a monospaced font (like \ttfamily).

For margin adjustments, consider using geometry, either setting margins at package load (via the optional argument), or via \geometry{...}. Margins can be set individually (left, right, top, bottom), in pairs (hmargin, vmargin) or as a whole (margin).

\documentclass{article}
\usepackage{lipsum}% Just for this example
\usepackage{multicol}
\usepackage[thinlines]{easytable}
\usepackage[margin=1in]{geometry}
\begin{document}
\begin{multicols}{2}
\lipsum[1]
\columnbreak
\begin{TAB}(b)[5pt]{|cccccccccc|}{|cccccccccc|}
  A & I & I & R & D & A & T & O & Y & T \
  C & O & M & M & U & T & A & T & O & R \
  P & S & Y & A & I & C & R & G & B & S \
  D & R & Q & U & O & T & I & E & N & T \
  E & O & A & A & B & E & L & I & A & N \
  M & I & D & C & O & A & P & A & A & H \
  I & T & U & P & R & O & D & U & C & T \
  M & O & N & G & W & A & R & T & T & T \
  R & T & T & A & P & I & T & O & A & T \
  S & E & M & I & G & R & O & U & P & C
\end{TAB}
\end{multicols}
\end{document}

Answer 2

The margin of the page can be reduced with the geometry package. An example is below:

\usepackage[letterpaper,inner=1in,outer=.75in,top=1cm,bottom=1.5cm]{geometry}
