[Tex/LaTex] How to center a big table in LaTeX

tables

I have a relatively large table composed the following way

\begin{table}[ht]
\caption{Backtesting - CFM $\alpha=5\%$, $confidence \ interval = 95\%$ }

\centering
\begin{tabular}{rrrrrrr}
  \hline
Bond & Expected Exceedances & Actual Exceedances & Test Statistic & Critical Value &  p-Value & Decision \\ 
  \hline
1 & 42.00 & 287.00 & 686.63 & 3.84 & 0.00 & Reject H0 \\ 
2 & 20.00 & 103.00 & 189.78 & 3.84 & 0.00 & Reject H0 \\ 
3 & 20.00 & 101.00 & 182.33 & 3.84 & 0.00 & Reject H0 \\ 
4 & 20.00 & 173.00 & 509.53 & 3.84 & 0.00 & Reject H0 \\ 
5 & 20.00 & 125.00 & 278.35 & 3.84 & 0.00 & Reject H0 \\ 
6 & 20.00 & 119.00 & 253.02 & 3.84 & 0.00 & Reject H0 \\ 
7 & 20.00 & 123.00 & 269.81 & 3.84 & 0.00 & Reject H0 \\ 
8 & 15.00 & 90.00 & 194.26 & 3.84 & 0.00 & Reject H0 \\ 
9 & 10.00 & 50.00 & 84.15 & 3.84 & 0.00 & Reject H0 \\ 
10 & 20.00 & 110.00 & 216.66 & 3.84 & 0.00 & Reject H0 \\ 
11 & 9.00 & 39.00 & 55.56 & 3.84 & 0.00 & Reject H0 \\ 
12 & 20.00 & 108.00 & 208.85 & 3.84 & 0.00 & Reject H0 \\ 
13 & 20.00 & 134.00 & 317.88 & 3.84 & 0.00 & Reject H0 \\ 
14 & 20.00 & 174.00 & 514.86 & 3.84 & 0.00 & Reject H0 \\ 
15 & 9.00 & 54.00 & 109.55 & 3.84 & 0.00 & Reject H0 \\ 
16 & 20.00 & 126.00 & 282.65 & 3.84 & 0.00 & Reject H0 \\ 
17 & 20.00 & 165.00 & 470.50 & 3.84 & 0.00 & Reject H0 \\ 
18 & 20.00 & 170.00 & 493.66 & 3.84 & 0.00 & Reject H0 \\ 
 \hline
\end{tabular}
\end{table}

in which having the \centering command does nothing to the output which is a table that is beyond the right corner of my page. Is there a way to center this table to fit my page? As I mentioned I tested having the \centering command and removing and the output was the same!

The main problem with your table is that quite a few of the entries in the header row are fairly long. I suggest you break them up across two lines. That way, it's only necessary to change the value of \tabcolsep -- the parameter that governs the amount of intercolumn whitespace -- to 5pt (default value: 6pt) to make the table fit comfortably inside the text block.

Instead of using r for all columns, you may want to use the S column type for the middle five columns, since they contain numbers that should be aligned on the respective decimal markers. You may also want to load the booktabs package and use its line-drawing macros instead of the generic \hline.

\begin{document}
\begin{table}[ht]
\setlength\tabcolsep{5pt} % default value: 6pt

15 &  9.00 &  54.00 & 109.55 & 3.84 & 0.00 & Reject H0 \\ 
16 & 20.00 & 126.00 & 282.65 & 3.84 & 0.00 & Reject H0 \\ 
17 & 20.00 & 165.00 & 470.50 & 3.84 & 0.00 & Reject H0 \\

\end{tabular}
\end{table}
\end{document}

Addendum: the variables "Expected Exceedances" and "Actual Exceedances" are integer-valued, right? If so, one shouldn't show the decimal fractional components of these variables (which, unsurprisingly, are .00 in all cases). Suppressing the display of the zero decimals may be achieved by setting the option zero-decimal-to-integer for columns of type S.

[Tex/LaTex] Big Table in latex

You can use the ltxtable latexpackage

This package is a wrapper around tabularx (that allows you to not specify the length of a column - for you the 4th one -) and longtable

By default the first line is repeated under all pages.

the main problem with this package is that the table needs to be written in another file. But you can do that like this:

\newcommand{\oldinput}[1]{\input{#1}}
\renewcommand{\input}[1]{#1}
\LTXtable{\linewidth}{%
  \begin{longtable}{cccXc}
  \end{longtable}
}
\renewcommand{\input}[1]{\oldinput{#1}}

If this pice of code is a little long you can set it into a command or environment (with the \newEnviron command provided by environ package) or \newenvironment and replace the LTXtable bracked with \bgroup and \egroup

[Tex/LaTex] tables without tabular

Don't engage in so much visual formatting. Instead, define some pertinent table parameters -- such as centering the column contents, the heights of the rows, etc -- beforehand, and then create a lean and reasonably easy to read table.

In the example below, I've created a dummy definition of your \VTGN macro to make the code compilable. You'll notice a complete absence of \vspace{3mm} and \cl directives in the code. Observe the use of \bigstrut to size the heights of the rows: it's an object with a depth of 4ex below the text baseline and a height of 6ex above the baseline. (The strut's total height is thus 10pt.) Adjust these parameters as needed to get the desired spacing. The strut's width is 0pt; hence it's not visible. One \bigstrut per row suffices.

enter image description here

\documentclass{article}
\usepackage[paperheight=28cm, paperwidth=20cm, margin=2cm]{geometry}
\newcommand\VTGN[1]{#1} %% just so that this example compiles
\usepackage{tabularx}
\newcolumntype{Y}{>{\centering\arraybackslash}X}
\newcommand\bigstrut{\rule[-4ex]{0pt}{10ex}}
\begin{document}
\noindent
\begingroup
\setlength\tabcolsep{0.1pt} % default: 6pt
\begin{tabularx}{\textwidth}{ | *{7}{Y|} }
\hline
\bigstrut & addition & subtraction & multiplication & division & exponentiation & rootification \\ 
\hline 
Vortigenu \bigstrut & \VTGN{+} & \VTGN{-} & \VTGN{*} & \VTGN{/} & \VTGN{\char"5E} & \VTGN{\char"40} \\ 
\hline
Earth \bigstrut & + & $-$ & $\times$ & $\div$ & ? & ? \\ 
\hline
\end{tabularx}
\endgroup
\end{document}

Addendum: I just noticed that you posted the following definition of the \VTGN macro:

\newcommand{\VTGN}[1]{\setmainfont{Vortigenu}{#1}\setmainfont{Times New Roman}}

Using \setmainfont in this manner is rather inefficient as well as quite complex; see Section 5 of the user guide of the fontspec package for a more in-depth explanation of this claim. I suggest you provide the following commands in the preamble:

\newfontfamily\vtgn{Vortigenu}
\newcommand\VTGN[1]{{\vtgn #1}} % Note the double curly braces

This definition of \VTGN makes it unnecessary to execute \setmainfont twice. Moreover, it works without having to know what the main document font happens to be.
