[Tex/LaTex] Alignment in tables using siunitx

horizontal alignmentsiunitxtables

I am using the siunitx package to align some numbers in a table. See below for preamble

\documentclass[12pt]{report}
 \usepackage[T1]{fontenc}
 \usepackage{textcomp}
 \usepackage{booktabs}
 \usepackage{multirow}
 \usepackage{siunitx}

\begin{document}
 \begin{table}[h]
  \centering
  \sisetup{table-format=2.4}
 \begin{tabular}{@{}lSSS@{}}
    \toprule
    \textbf{Summary statistics} & \textbf{Stock1} & \textbf{Stock2} & \textbf{Stock3} \\ \midrule
    Mean                        & -0.0003       & -0.0007          & -0.0008           \\ \midrule
    Maximum                     & 0.1379           & 0.2028           & 0.0924            \\
    Minimum                     & -0.2166          & -0.1164          & -0.1306           \\ \midrule
    Standard deviation          & 0.0238           & 0.0159           & 0.0128            \\
    Skewness                    & -0.0419          & 0.4084           & -1.2155           \\
    Kurtosis                    & 6.7156           & 18.8598          & 13.5484   \\ \midrule
    Jarque-Bera                 & \multicolumn{1}{c}{11,048}  & \multicolumn{1}{c}{39,311}  & \multicolumn{1}{c}{21,206}  \\
    P-value                     & \textless 0.0001  & \textless 0.0001  & \textless 0.0001   \\ \midrule
    Observations                & \multicolumn{1}{c}{4,438}   & \multicolumn{1}{c}{2,643}   & \multicolumn{1}{c}{2,349}   \\ \bottomrule
 \end{tabular}
  \caption{{\small Summary statistics of the log returns}}
  \label{tab:SumStat}
 \end{table}
\end{document}

Output

I am able to align decimal numbers in the table correctly, but I also have one row of integer numbers and one row with a \textless command (the two bottom rows). My problems are:

I want the integer numbers to be aligned as centered below the decimal numbers as possible (see the column for stock3 especially). I have tried using alignment r, but that pushes the number too far to the right. Is it possible to align the number something in between c and r, maybe?
I want some spacing between the textless sign and the decimal number.

I would be grateful for any help!

Even though I'd do some things a little bit different myself, I will simply answer the specific questions you asked.

To get the integer numbers centered in the column, wrap them in a group as in {4,438}, as these groups are not parsed by siunitx. Also, I wrapped your column headings in groups to get them centered. Optionally you can use \sisetup{table-format=2.4,group-separator={,},group-four-digits} with \num{4438} to make switching format later easier. If you want these numbers right-aligned, you can set table-text-alignment=right in the column setup. Note that this will also affect the column headings.
To get better spacing after <, use \sisetup{table-format=<2.4}.

In conclusion, you can use the following (removed non-essential packages):

    Maximum                     &  0.1379           &  0.2028           &  0.0924           \\

[Tex/LaTex] How to use siunitx and tabularx together

The X column in tabularx is then converted to p{<width>} where width is automatically calculated. You can change this by redefining the \tabularxcolumn macro like described in the package manual:

\renewcommand{\tabularxcolumn}[1]{<column definition where #1 is the width>}

The S column uses the c column internally. To replace this with p{<width>} you have to manually place the internal column definition of S into \tabularxcolumn. The following code worked in my tests.

\documentclass{article}

\usepackage{array}
\usepackage{tabularx}
\usepackage{siunitx}


\begingroup
% Allow `_` and `:` in macro names (LaTeX3 style)
\catcode`\_=11
\catcode`\:=11
% Internal code of `S`
\gdef\tabularxcolumn#1{%
    >{\__siunitx_table_collect_begin:Nn S{} }%
    p{#1}%  <- this is different (is `c` in normal `S`)
    <{\__siunitx_table_print:}%
}
\endgroup

\begin{document}

\begin{tabularx}{\textwidth}{p{1.5cm} XXX}
     bla & 1.23 & 4.5  & 67.89 \\
     bla & 1.2  & 4.50 &  7.89 \\
     bla &  .2  &  .50 & 67.8 \\
\end{tabularx}
\end{document}

[Tex/LaTex] using the package siunitx

The main error is in the wrong table preamble:

\begin{tabular}{l c c c c }{S[S[tabnumalign=center,tabformat=3.2]}

makes no sense; you have to specify S[<options>] just like a c or l column; so

\begin{tabular}{
  @{}
  l
  S[table-format=2.3]
  S[table-format=2.3]
  S[table-format=2.0]
  S[table-format=2.0]
  @{}
 }

to get a left aligned column, with four numeric columns with the indicated format for numbers (digits for the integer part and digits for the decimal part).

You have several \smallskip commands that only add noise to the table; just use the standard line spacing, adding horizontal rules for dividing the blocks; I also used italics for the subtitles, in order to emphasize them as not really rows of the table.

Finally, I used \small because the table is quite large; I also reduced a bit the separation between columns (this might be unnecessary, depending on the pagination parameters of your document).

Also the text of a caption shouldn't have a surrounding \textbf command: do the setup with \captionsetup.

\documentclass{article}

\usepackage{siunitx}
\usepackage{booktabs}
\usepackage[labelfont=bf]{caption}

\captionsetup{font=bf}
\newcommand*{\MyIndent}{\hspace*{1.5cm}}
