Table cell color overlaps cell border

Question

As the graphic and MWE below show, some of colored my table cells are obscured the cell colors. I'd appreciate help fixing this.

Table with colored cells

\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage[table]{xcolor}

\makeatletter
\providecommand{\tabularnewline}{\\}
\makeatother

\usepackage{babel}
\begin{document}
\begin{tabular}{c|c|c|c|cc|}
\multicolumn{1}{c}{} & \multicolumn{1}{c}{A} & \multicolumn{1}{c}{B} & \multicolumn{1}{c}{C} & D & \multicolumn{1}{c}{E}\tabularnewline
\cline{2-6} 
a & \cellcolor{blue!25} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} &  & \cellcolor{red!25} \tabularnewline
\cline{2-3} 
b &  &  & \multicolumn{1}{c}{} &  & \tabularnewline

You can use hhline here which simply adds vertical space and doesn’t get over-drawn by \cellcolor.

Code

\documentclass{standalone}
\usepackage[table]{xcolor}
\usepackage{hhline}
\begin{document}
\begin{tabular}{c|c|c|c|cc|}
    \multicolumn{1}{c}{} & \multicolumn{1}{c}{A} & \multicolumn{1}{c}{B} & \multicolumn{1}{c}{C} &           D           & \multicolumn{1}{c}{E} \tabularnewline \hhline{~|*{5}{-}}
             a           &  \cellcolor{blue!25}  & \multicolumn{1}{c}{}  & \multicolumn{1}{c}{}  &                       &  \cellcolor{red!25}   \tabularnewline \cline{2-3}
             b           &                       &                       & \multicolumn{1}{c}{}  &                       &  \tabularnewline \cline{2-4}
             c           &                       &                       &                       &                       &  \tabularnewline \cline{2-5}
             d           &                       &                       &                       & \multicolumn{1}{c|}{} &  \tabularnewline \hhline{~|*5-}
             e           &                       & \cellcolor{green!25}  &                       & \multicolumn{1}{c|}{} &  \tabularnewline \hhline{~|*5-}
\end{tabular}
\end{document}

This doesn't fix the problem for me. The borders are still overlapped when I try the provided code. — Code, Jan 19 '20 at 17:43

The environment {NiceTabular} of the package nicematrix has tools design to address that kind of problem.

\documentclass[margin=1cm]{standalone}
\usepackage{nicematrix}
\usepackage{xcolor}
\begin{document}
\begin{NiceTabular}{ccccc}[first-row,first-col,hvlines]
\CodeBefore
  \cellcolor{blue!25}{1-1}
  \cellcolor{red!25}{1-5}
  \cellcolor{green!25}{5-2}
\Body
  & A & B & C & D & E \
a &   & \Block{1-}{} & \Block{2-1}{} & \Block{3-1}{} & \Block{4-1}{} \
b &   &   & \Block{1-}{} \
c &   &   &   & \Block{1-}{} \
d &   &   &   &   & \Block{1-}{} \
e \
\end{NiceTabular}
\end{document}

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