Adjust table width without messing up preliminary set by paper guidelines

Question

Hi I am in the midst of publishing paper to IJNT. I downloaded the page guidelines from the corresponding website. The only problem I am having is that I could not adjust the table to fit the page margin set by IJNT. Below is the code for my table

    \documentclass[12pt,a4paper,twoside]{report}
\usepackage{tabularx,ragged2e,booktabs,caption}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{bm}
\begin{document}
\begin{table}
    \centering
    \def\arraystretch{3.0}
    \begin{scriptsize}
    \begin{tabular}{|c|c|c|}
    \cline{1-3}
     $\mu \in Y$ & $\mu P \oplus T'$  & $Z(nP)$ \\ \cline{1-3}
    $-4$ & $\bigg(\dfrac{4482}{361}\beta + \dfrac{3489}{361}, \dfrac{-52002}{6859}\beta + \dfrac{2057238}{6859}\bigg)$  & $2^{22}\cdot3^{44}\cdot19^{-32}\cdot \bm{13\cdot1789}\cdot[-46931113911612188165\beta + 242506871209270916181]^2$  \\ \cline{1-3}
    $-3$ & $\bigg(\dfrac{-99}{8}\beta + \dfrac{93}{8}, \dfrac{-81}{16}\beta - \dfrac{5049}{16}\bigg)$  & $2^{-32}\cdot3^{34}\cdot\bm{5\cdot29}\cdot\bigg[\dfrac{-143654012463}{2}\beta + \dfrac{596091741497}{2}\bigg]^2$  \\ \cline{1-3}
     $-2$ & $(162\beta + 681,-5994\beta - 24786)$ & $[2^{13}\cdot3^{22}\cdot5\cdot19\cdot379\cdot1433\cdot1481\beta + 2^{13}\cdot3^{23}\cdot199\cdot527732929]^2$\\ \cline{1-3}
    $-1$ & $(-18\beta + 69, -162\beta + 918)$  & $2^{24}\cdot3^{34}\cdot\bm{5\cdot29}\cdot[95293 +23052\beta]^2$  \\ \cline{1-3}
    $0$ & $\bigg(\frac{3}{2}(-5 - 9\beta),0\bigg)$  & $2^{10}\cdot 3^{44}\cdot \bm{13\cdot1789}\cdot[21\beta + 7]^2 $  \\ \cline{1-3}
    $3$ & $\bigg(\dfrac{-99}{8}\beta + \dfrac{93}{8}, \dfrac{81}{16}\beta + \dfrac{5049}{16}\bigg)$  & $2^{-32}\cdot3^{34}\cdot\bm{5333\cdot97324757}\cdot\bigg[\dfrac{2188485}{2}\beta + \dfrac{12121421}{2}\bigg]^2$  \\ \cline{1-3}
    \end{tabular}
\end{scriptsize}
    \caption{$Z(\widetilde{Q})$ a square for $\mu \in Y$.\label{znpsquare}}
    \end{table}

\end{document}

Is there a way, (without messing up with their preliminaries), I can adjust this table to fit the margin. I have attach an image for the table generated.

Answer 1

as i said in comment, your table with one line equation is to wide. reasonable solution is break equation into more line. for example with help of multlined from mathtools package:

\documentclass[12pt,a4paper,twoside]{report}
\usepackage{array, makecell}
\setcellgapes{5pt}
\usepackage{mathtools}

%-------------------------------- show page layout, only for test
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%

\begin{document}
    \begin{table}

\setlength\arraycolsep{3pt}

    \caption{$Z(\widetilde{Q})$ a square for $\mu \in Y$.}
\label{znpsquare}
    \end{table}
\end{document}

which gives:

in code i make some changes as:

• tabular is replaced by array which is encapsulated in math environment
• for boldface variables \mathbf{...} is used
• more vertical space around math expression is obtain by \makegapedcells from package makecell in preamble are loaded only packages needed for setting this table
