Centering the latex table in the page - latex

Question

I have the following table in LaTeX, and although I have used the \centering in the code, it is not centred when knitted. In addition it extends more than the text width as shown in the figure below
\begin{table}[H]
\centering
\caption[mnodels summary]{Summary results of the models \label{tab:modelssummary}}
\begin{tabular}{cccccc}
\toprule
\multicolumn{6}{c}{~ \textbf{~~Models Performance }} \\
\hline
\textbf{Model} & \textbf{Residual Mean} & \textbf{Constant Variance} & \textbf{Autocorrelation} & \textbf{Adj. R-Squared} & \textbf{AIC} \\
\hline\hline
\textbf{Model 1} & OK & OK & YES & 0.83 & 4804.8 \\
\textbf{Model 2} & OK & OK & YES & 0.84 & 4569.5 \\
\textbf{Model 3} & OK & OK & YES & 0.83 & 4763.7 \\
\textbf{Model 4} & OK & OK & YES & 0.87 & 3760.5 \\
\textbf{Model 5} & OK & OK & YES & 0.86 & 3964.5 \\
\textbf{Model 6} & No & No & YES & 0.32 & 10879.7~ \\
\textbf{Model 7} & No & No & YES & 0.80 & 5434.2 \\
\bottomrule
\end{tabular}
\end{table}
and it will look like this:
How can I resolve this?

Answer 1

If you accept multi lines in headings and abbreviations, you can squeeze the table and even fit within the default latex page. Then, \centering will work
and the code
\documentclass{article}
\usepackage{booktabs}
\usepackage{caption}
\captionsetup[table]{position=top,skip=6pt}
\usepackage{makecell}
\usepackage{ragged2e} % Centering
\usepackage{siunitx} % S[...]
% Makecell - settings
\renewcommand\theadfont{\normalsize\normalfont\bfseries}
\renewcommand\theadalign{tc}
% Custom column types
\newcolumntype{C}{>{\Centering\bfseries}p{1.4cm}}
\newcolumntype{P}[1]{>{\Centering}p{#1}}
\begin{document}
\begin{table}[tbh]
\centering
\setlength\tabcolsep{0pt}
\caption[mnodels summary]{Summary results of the models}\label{tab:modelssummary}
\begin{tabular}{
C #{\hspace{1em}}
*4{P{1.25cm}}
#{\hspace{0.75em}}
S[group-minimum-digits=4,table-format=4.1]
}
\toprule
& \multicolumn{5}{c}{\textbf{Models Performance}} \\
\cmidrule{2-6}
\thead{Model}
& \thead{Resid.\\Mean}
& \thead{Const.\\Var.}
& \thead{Auto\\corr.}
& \thead{Adj.\\R\textsuperscript{2}}
& {\thead{AIC}} \\ % {} required for S[] to work
\midrule\midrule
1 & OK & OK & YES & 0.83 & 4804.8 \\
2 & OK & OK & YES & 0.84 & 4569.5 \\
3 & OK & OK & YES & 0.83 & 4763.7 \\
4 & OK & OK & YES & 0.87 & 3760.5 \\
5 & OK & OK & YES & 0.86 & 3964.5 \\
6 & No & No & YES & 0.32 & 10879.7 \\
7 & No & No & YES & 0.80 & 5434.2 \\
\bottomrule
\end{tabular}
\end{table}
