Nice tables in beamer presentation

Question

I liked the approach shown here. beautiful tables in latex. But when I use it in beamer class, tabularx conflicts with xcolor. What is the solution?

Answer 1

Beamer loads xcolor by itself. So if you want to use specific xcolor options (and the approach does) you have to pass them to beamer and not load xcolor again with these settings.

\documentclass[xcolor=usenames,dvipsnames]{beamer} % <-- set xcolor options here

\usepackage{tcolorbox}
\usepackage{tabularx}
\usepackage{array}
\usepackage{colortbl}
\tcbuselibrary{skins}

\newcolumntype{Y}{>{\raggedleft\arraybackslash}X}

\tcbset{tab1/.style={fonttitle=\bfseries\large,fontupper=\normalsize\sffamily,
colback=yellow!10!white,colframe=red!75!black,colbacktitle=Salmon!40!white,
coltitle=black,center title,freelance,frame code={
\foreach \n in {north east,north west,south east,south west}
{\path [fill=red!75!black] (interior.\n) circle (3mm); };},}}

\tcbset{tab2/.style={enhanced,fonttitle=\bfseries,fontupper=\normalsize\sffamily,
colback=yellow!10!white,colframe=red!50!black,colbacktitle=Salmon!40!white,
coltitle=black,center title}}

\begin{document}
\begin{frame}{Nice Tables}
\begin{tcolorbox}[tab2,tabularx={X||Y|Y|Y|Y||Y}]
Group & One     & Two     & Three    & Four     & Sum      \\\hline\hline
