Well fit tables in LaTeX is hard for me, and I don't know if there is a manual with good practices about it. I need to create a table with S columns contending numbers, but the header of those columns are very long and I can't find a way to fit it into the page with the tricks learned here.
My MWE could be something like:
\documentclass[fontsize=11pt,paper=letter,headings=small,bibliography=totoc,DIV=9,headsepline=true]{scrartcl}
\usepackage[utf8]{inputenx}
\usepackage[TS1,T1]{fontenc}
\usepackage{textcomp}
\usepackage[spanish,mexico]{babel}
\usepackage[intlimits]{amsmath}
\usepackage{xspace}
\usepackage{xkeyval}
\usepackage{array,multirow,tabularx,ragged2e,booktabs}
%\newcolumntype{Y}{>{\RaggedRight\arraybackslash\hspace{0pt}}X}
\newcolumntype{Y}{>{\RaggedRight\arraybackslash}X}
%\newcolumntype{C}{>{\centering\arraybackslash\hspace{0pt}}X}
\usepackage{rotating}
\usepackage{colortbl}
\usepackage[per-mode=symbol]{siunitx}
\sisetup{
output-decimal-marker = {,},
range-units = brackets,
list-final-separator = { \translate{and} },
list-pair-separator = { \translate{and} },
range-phrase = { \translate{to (numerical range)} },
}
\ExplSyntaxOn
\providetranslation [ to = Spanish ]
{ to~(numerical~range) } { a }%substitute the right word here
\ExplSyntaxOff
\begin{document}
\begin{table}[htb]
\caption{Capacidad de generación eléctrica en México}
\label{tab:CGE}
\centering
\begin{tabularx}{\textwidth}{@{} l S S[table-format=6.2] S[table-format=3.2]@{}}

As you can see my first issue is to fit the table inside the page. The second one is put in boldface the units in the title row. A third issue is to add a column in the left side of the table to specify the public and private generation, bit I think that could be easy to solve after the first one.
Sorry if this is a duplicate question, but I didn't found an answer in the questions I was reading before to ask.
