[Tex/LaTex] Create a table with LaTeX

tables

I need to copy a table from a pdf file to my LaTeX document. I know I have to do it by hand but still don't understand how to create a table with LaTeX.

I need to translate this table back to its LaTeX commands

Here, the figure labels are printed as Table x.y where x is the section number and y is a table number within section x.

\documentclass{article}

\usepackage[hmargin=3cm,vmargin=3.75cm]{geometry} % Here, only used to get rid of a overfull \hbox warning.
\usepackage{booktabs,dcolumn}                     % Tables.
\usepackage[figureposition=bottom]{caption}       % Float captions.

% Globally set table float position.
\makeatletter
  \providecommand*\setfloatlocations[2]{\@namedef{fps@#1}{#2}}
\makeatother
\setfloatlocations{table}{htbp}

% Redefine table counter.
\makeatletter
  \@addtoreset{table}{section}
\makeatother
\renewcommand*\thetable{\arabic{section}.\arabic{table}}

% Simplify notation.
\newcolumntype{d}[1]{D{.}{.}{#1}}
\newcommand*\mc[1]{\multicolumn{1}{c}{#1}}
\newcommand*\mcTwo[1]{\multicolumn{2}{l}{#1}}

Update

Another way of creating the table is using the S column from siunitx;

\documentclass{article}

\usepackage[
%  locale = DE % if you want a comma as decimal separator instead of a dot
]{siunitx}
%\usepackage[version = 3]{mhchem} % typesetting chemical formulae using \ce{}
\usepackage{booktabs}

\newcommand*\mcTwo[1]{\multicolumn{2}{l}{#1}}

\begin{document}

\begin{tabular}{
  c
  *{3}{S[table-format = 2.1]}
  *{2}{S[table-format = 1.1]}
       S[table-format = 1.2]
  *{4}{S[table-format = 1.1]}
       S[table-format = 1]
       S[table-format = 1.2]
}

(Personally, I prefer this method.)
