Linha horizontal nas tabelas que chegam na classe de documento do artigo, mas não são visíveis no beamer

Question

A tabela a seguir (Como remover linha preta extra que entra na tabela devido ao hhline) está funcionando bem na classe de documento article, mas as linhas horizontais da tabela não são visíveis na beamerclasse.

\documentclass{article}
 \usepackage{hhline}
  \usepackage[table, svgnames]{xcolor}

  \usepackage{multirow}
 \usepackage{booktabs}

 \definecolor{Aliceblue}{rgb}{0.94, 0.97, 1.0}
\definecolor{aliceblue}{rgb}{0.94, 0.97, 1.0}

\definecolor{babyblue}{rgb}{0.54, 0.81, 0.94}

    \rowcolor{aliceblue} PQR                                                                 & 0.65       & 0.753     & 2.064       & 2.231      & 28.04       & 28.56       \\ \hhline{-|*6-}

Como faço para que as linhas horizontais beamertambém fiquem visíveis no ambiente?

Answer 2

É fácil fazer essa tabela com {NiceTabular}of nicematrix.

\documentclass[xcolor]{beamer}
\usepackage{nicematrix}


\definecolor{aliceblue}{rgb}{0.94, 0.97, 1.0}
\definecolor{babyblue}{rgb}{0.54, 0.81, 0.94}

\begin{document}
\begin{frame}
\begin{table}[ht]
\centering
\setlength{\arrayrulewidth}{1.3pt}
\footnotesize
\setlength{\tabcolsep}{2.7 pt}
\renewcommand{\arraystretch}{1.4}
\begin{NiceTabular}{ccccccc}[hvlines]
\CodeBefore
  \rowcolors{1}{babyblue}{aliceblue}
\Body
  \Block[fill=aliceblue]{2-1}{Methods} & \Block{1-2}{ISE} && \Block{1-2}{IAE} && \Block{1-2}{ITAE} \\ 
      &$-$20\%   & +20\%  & $-$20\%  & +20\% & $-$20\% & +20\%  \\
  ABC & 0.5645 & 0.63   & 1.8    & 1.8   & 6.1   & 6.6    \\ 
  XYZ & 2.1    & 2.3    & 0.881  & 9.82  & 9.2   & 28.9   \\ 
  MNO & 0.68   & 0.97   & 1.62   & 1.61  & 8.9   & 8.2    \\ 
  PQR & 0.65   & 0.753  & 2.064  & 2.231 & 28.04 & 28.56  \\ 
\end{NiceTabular}
\end{table}
\end{frame}
\end{document} 

Você precisa de várias compilações (porque nicematrixusa nós PGF/Tikz nos bastidores).
