Best Answer

You need to load table option of xcolor, which loads colortbl containing \cellcolor, etc.

\documentclass[12pt,a4paper]{report}
\usepackage[locale=FR]{siunitx}
\usepackage{booktabs}
\usepackage[table]{xcolor}
\begin{document}
\noindent
\textbf{Konvergence - MOST a BRITE}
\begin{table}[h!!]
\renewcommand{\arraystretch}{1.45}
\scriptsize
\begin{tabular}{r|S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]S[table-format=5.6,table-auto-round]}
Fit&    1&  2&  3&  4&  5&  6&  7&  8&  9& \cellcolor{blue!25}10 &  11\\
\end{tabular}
\end{table}
\end{document}

Btw why is your table so wide?
