# Change the margins for a page with a table

I'm trying to change the margin of a page containing a table so that the table start after 1cm from left and right. I found this solution but when I tried it, it only changes one side of the table. Does anyone know how to change it for both sides?!

\documentclass{article}

\usepackage[margin=2.3cm]{geometry} %The margin for the whole document

\usepackage{color, colortbl}
\usepackage{caption}

\captionsetup[table]{skip=5pt}

\usepackage{enumitem, etoolbox, tabularx, makecell, booktabs}
\makeatletter
\newcommand*{\compress}{\@minipagetrue}
\makeatother

\begin{document}

You can find table \ref{table:Mytable} on page \pageref{table:Mytable}.

\newpage

\definecolor{Gray}{gray}{0.9}

\begin{table}[!htbp]

\caption{My table}
\label{table:Mytable}

{\renewcommand{\arraystretch}{3}
\setlist[itemize]{wide=0pt, leftmargin=*, topsep=0pt, after=\vspace*{-\baselineskip}}
\AtBeginEnvironment{itemize}{\compress}

\hspace*{-1cm}\begin{tabularx}{\linewidth}{X *{3}{p{20mm}} p{18mm}p{42mm}}
\rowcolor{Gray}
\toprule
& \textbf{\thead{Column \\ 2}} & \textbf{\thead{Column \\ 3}} & \textbf{\thead{Column \\ 4}} & \textbf{\thead{Column \\ 5}} & \textbf{\thead{Column \\ 6}} \\
\midrule

%Row1
entry1 & \centering entry2 & \centering entry3 & \centering  entry4 & \centering entry5 & \begin{itemize} \item entry6.1 \item  entry6.2  \end{itemize}
\\

\bottomrule
\end{tabularx}\hspace*{-1cm}}

\end{table}

\newpage

\end{document}
• What do you mean with margin of the table? Your table leaks into the left margin, which is the consequence of \hspace*{-1cm}... – user31729 Jun 4 '17 at 22:10
• @ChristianHupfer I meant that the table has to start after 1cm from each side. – F 505 Jun 4 '17 at 22:12
• You should probably use a \newgeometry statement, with respective margin settings, but please note that that \newgeometry will ship a new page first – user31729 Jun 4 '17 at 22:22
• @Christian Hupfer: Why did you delete your answer, which is what I would have posted, had you not done it before? – Bernard Jun 4 '17 at 22:55
• @Bernard: Because I think I have misunderstood the question -- I think that the O.P wants the page margins should be changed, not the shifting of the table inwards. – user31729 Jun 4 '17 at 22:56

You need to increase the width of the table by the same amount 2cm by setting \begin{tabularx}{\dimexpr\linewidth+2cm}.

\documentclass{article}
\usepackage[margin=2.3cm]{geometry} %The margin for the whole document
\usepackage{color, colortbl}
\usepackage{caption}
\captionsetup[table]{skip=5pt}
\usepackage{enumitem, etoolbox, tabularx, makecell, booktabs}
\makeatletter
\newcommand*{\compress}{\@minipagetrue}
\makeatother

\begin{document}
You can find table \ref{table:Mytable} on page \pageref{table:Mytable}.
\newpage
\definecolor{Gray}{gray}{0.9}
\begin{table}[!htbp]
\caption{My table}
\label{table:Mytable}
{\renewcommand{\arraystretch}{3}
\setlist[itemize]{wide=0pt, leftmargin=*, topsep=0pt, after=\vspace*{-\baselineskip}}
\AtBeginEnvironment{itemize}{\compress}
\hspace*{-1cm}\begin{tabularx}{\dimexpr\linewidth+2cm}{X *{3}{p{20mm}} p{18mm}p{42mm}}
\rowcolor{Gray}
\toprule
& \textbf{\thead{Column \\ 2}} & \textbf{\thead{Column \\ 3}} & \textbf{\thead{Column \\ 4}} & \textbf{\thead{Column \\ 5}} & \textbf{\thead{Column \\ 6}} \\
\midrule
%Row1
entry1 & \centering entry2 & \centering entry3 & \centering  entry4 & \centering entry5 & \begin{itemize} \item entry6.1 \item  entry6.2  \end{itemize}   \\
\bottomrule
\end{tabularx}\hspace*{-1cm}}
\end{table}
\newpage

\end{document}

The adjustwidth environment, from changepage is done for that. In addition, I removed the white strips at top and bottom of the coloured row due to the padding around booktabs rules:

\documentclass{article}

\usepackage[margin=2.3cm, showframe]{geometry} %The margin for the whole document

\usepackage{color, colortbl}
\usepackage{caption}
\usepackage{changepage}
\captionsetup[table]{skip=5pt}

\usepackage{enumitem, etoolbox, tabularx, makecell, booktabs}
\makeatletter
\newcommand*{\compress}{\@minipagetrue}
\makeatother

\begin{document}

You can find table \ref{table:Mytable} on page \pageref{table:Mytable}.

\newpage

\definecolor{Gray}{gray}{0.9}

\begin{table}[!htbp]
