Why is `hiderowcolorstest` and `showrowcolorstest` not defined with `xcolor` loaded?

I try to compile this simple MWE:

documentclass{article}

usepackage[table]{xcolor}
usepackage{array}

begin{document}
rowcolors[hline]{3}{green!25}{yellow!50}
arrayrulecolor{red!75!gray}
begin{tabular}{ll}
    test & row numberrownum
    test & row numberrownum
    test & row numberrownum
    test & row numberrownum
    arrayrulecolor{black}test & row numberrownum
    test & row numberrownum
    rowcolor{blue!25}test & row numberrownum
    test & row numberrownum
    hiderowcolorstest & row numberrownum
    test & row numberrownum
    showrowcolorstest & row numberrownum
    test & row numberrownum
    multicolumn{1}{>{columncolor{red!12}}l}{test} & row numberrownum
end{tabular}
end{document}

Which is straight from the documentation of xcolor, but I get: Undefined control sequence. hiderowcolorstest and showrowcolorstest

Any hints, what I am doing wrong?
