[Tex/LaTex] tabularx option in tcolorbox

tabularxtcolorbox

I'd like to use the recently introduced (in version 2.10) tabularx key for the tcolorbox package. The key is documented in the tcolorbox documentation, section 3.6, paragraph /tcb/tabularx, page 28.
I have the latest versin of the package (2.20).

I can't seem to reproduce the examples given there nor a simplified one like this:

\documentclass{article}
\usepackage{array,tabularx}
\usepackage{tcolorbox}
\begin{document}

\begin{tcolorbox}[tabularx={X|X},title=table]
cell A & Cell B\\\hline
cell C & Cell D
\end{tcolorbox}

\end{document}

What I got is an undefined control sequence error in \begin{tcolorbox}[tabularx={X|X},title=table] and this output:
enter image description here

The colorname printed in the left side is the default value of the colframe option, i.e., if you add colframe=red in the tcolorbox options, the word "red" will be printed out.
Am I hitting a bug or did I miss something?

There appears to be a dependency on colortbl

enter image description here

\documentclass{article}
\usepackage{array,tabularx,colortbl}
\usepackage{tcolorbox}
\begin{document}

\begin{tcolorbox}[tabularx={X|X},title=table]
cell A & Cell B\\\hline
cell C & Cell D
\end{tcolorbox}

\end{document}

[Tex/LaTex] Multipage table using tcolorbox and tabularx

Here is my addition to David Carlisle's answer. I sorted things a little bit different and added some options which might be useful. Especially, the right edge problem is resolved and the caption put into the title.

enter image description here

Here is the code:

\documentclass{article}
\usepackage{blindtext}
\usepackage{tcolorbox}
\tcbuselibrary{breakable,skins}

[Tex/LaTex] Tabularx option in tcolorbox: how to colored the first row

Try the before upper app={\rowcolor{yellow!30!white} key -- code which is introduced before the first line of tabularx is shipped out.

(See section 18.1 'hooks' of the current (3.72) manual of tcolorbox)

\documentclass[border=5mm,
preview]{standalone}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage[dvipsnames,svgnames,table]{xcolor}
\usepackage{makecell,tabularx}
\newcolumntype{L}{>{\raggedright\arraybackslash}X}
\usepackage[many]{tcolorbox}
\newtcolorbox{tctabularx}[1]{%
  enhanced,
  fonttitle=\sffamily\bfseries, fontupper=\small\sffamily,
  arc=0mm,
  colback=yellow!10!white, colframe=red!50!black,
  #1,before upper app={\rowcolor{yellow!30!white}}
                    }% end tctabularx

\begin{document}
\begin{tctabularx}{tabularx={L|L}} 
  \thead{FIR}
  &   \thead{IIR}                         \\
  \hline

     (ulomek dveh polinomov)             \\

     zahtevnejša izvedba
     &   manj zahtevna izvedba               \\
   \end{tctabularx}
