In my table I have used \cellcolor[gray]{0.8} and I would like to mark some words in my text with the same color. I have tried \colorbox{gray}, but the resulting box in the text is too dark. How can I get the same grey-color as in the table?
[Tex/LaTex] Equivalent color for \colorbox{gray} as for \cellcolor[gray]{0.8}

\tabcolsep is a length so you can set
\setlength\tabcolsep{5pt}
before the table to set the spacing between columns, then use a smaller amount (such as 0pt in the color optional arguments so perhaps
\cellcolor{green}[1pt]
note it has to have a unit such as pt not a number as in the examples in your question.
I'd simply put the tabular inside a \colorbox:
\documentclass{article}
\usepackage{booktabs,xcolor,siunitx}
\definecolor{lightgray}{gray}{0.9}
\begin{document}
\begingroup\setlength{\fboxsep}{0pt}
\colorbox{lightgray}{%
\begin{tabular}{l*{4}{S[table-format=3.2]}@{}}
\toprule
Method & \multicolumn{4}{c}{Recognition rate (\%) vs.\ illumination} \\
\cmidrule{2-5}
& \multicolumn{1}{c}{Subset 2} &
\multicolumn{1}{c}{Subset 3} &
\multicolumn{1}{c}{Subset 4} &
\multicolumn{1}{c}{Subset 5} \\
\midrule
Linear subspace [9] & 100.00 & 100.00 & 85.00 & {n/a} \\
Cones-attached [9] & 100.00 & 100.00 & 91.40 & {n/a} \\
Cones-cast [9] & 100.00 & 100.00 & 100.00 & {n/a} \\
PCA & 98.33 & 79.17 & 30.00 & 15.79 \\
LTV${}+{}$PCA & 100.00 & 99.17 & 96.43 & 92.11 \\
Our method${}+{}$PCA & 100.00 & 100.00 & 100.00 & 100.00 \\
\bottomrule
\end{tabular}%
}\endgroup
\end{document}
The local setting of \fboxsep is needed to avoid padding.

The arguments to
\cellcolorare just passed to\colorinternally so that it colours the panel of the specified colour sojust calls
and you may use that directly.
