Why does transparent not work well in XeLaTeX and how can I fix it?

Question

I'm looking for a semi transparent black background on certain table rows in a pdf document.

I have tried to apply https://tex.stackexchange.com/a/62528/23302 and it works if I use pdflatex. But I have to use XeLaTeX; however, it produces error message

! Undefined control sequence.
\CT@do@color ...mc \kern -\@tempdimb \transparent
                                                  {0.5}\leaders \vrule \hski...
l.36 \rowcolor{black}Date &
                            Value\tabularnewline
