How to make an horizontally large table fit into the output?

Question

I am trying to fit an horizontally large table in the PDF output... Acting on the size inches of each column does not help so far. Any suggestion?

Here is the code:

\documentclass{article}
\usepackage[left=2.54cm, right=2.54cm,top=2.54cm,bottom=2.54cm]{geometry}

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

Please, consider the first row of the table, as I did not fill in the rest yet.

Try the following:

\usepackage{booktabs, makecell, tabularx}
    \renewcommand\theadfont{\bfseries}
    \renewcommand\theadgape{}
\usepackage{siunitx} % considered is v3
\begin{document}
\begin{table}[ht]

\centering
\footnotesize
\sisetup{table-format=-1.2,
        table-space-text-post={%},
        }
\setlength\tabcolsep{2.2pt}
\caption{DDQRL}\label{tab:2}
\begin{tabularx}{\linewidth}{@{} X *{11}{S} @{}}
