Horizontal line in tables coming in article document class but not visible in beamer

Question

The following table (How to remove extra black line coming in table due to hhline) is working fine in document class article but, the horizontal lines of table are not visible in beamer class.

\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}

 \begin{document}

  \begin{table}[ht]
\centering
\setlength\arrayrulewidth{1.3pt}
\footnotesize\setlength{\tabcolsep}{2.7 pt}
\renewcommand{\arraystretch}{1.4}
\begin{tabular}{|c|c|c|c|c|c|c|}
    \hline
    \cellcolor{aliceblue}  & \multicolumn{2}{c|}{\cellcolor{babyblue}ISE} & \multicolumn{2}{c|}{\cellcolor{babyblue}IAE} & \multicolumn{2}{c|}{\cellcolor{babyblue}ITAE} \\

    \rowcolor{babyblue}ABC                                                           & 0.5645      & 0.63     & 1.8       & 1.8      & 6.1       & 6.6       \\ \hhline{-|*6-}

    \rowcolor{babyblue}MNO                                                                & 0.68      & 0.97     & 1.62       & 1.61      & 8.9       & 8.2       \\ \hhline{-|*6-}
    \rowcolor{aliceblue} PQR                                                                 & 0.65       & 0.753     & 2.064       & 2.231      & 28.04       & 28.56       \\ \hhline{-|*6-}
\end{tabular}
\end{table}
\end{document}

How do I make the horizontal lines to be visible in beamer environment as well?

Add this : \makeatletter\let\zz\reset@color\def\reset@color{\kern\z@\zz}\makeatother in your preamble as described here: https://tex.stackexchange.com/a/405021/120578 — koleygr, Mar 04 '19 at 12:24

It's easy to do that table with {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}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).
