how can shading rows in table

Question

I wanted to do shading in a table according to its rows. For example, if you see the table below:
a  b   c   d 
a 90 10  0   0
b 0  80  10  10
c 0  0   95  5
d 0  10  5   85

I want to shade automatically each rows. Here is a code from (Parametrize shading in table through TikZ)
and I want this theme
documentclass[english]{article}
usepackage[T1]{fontenc}
usepackage[latin9]{inputenc}
usepackage{babel}
usepackage[table]{xcolor}
usepackage{collcell}
usepackage{hhline}
usepackage{pgf}
usepackage{multirow}

defcolorModel{hsb} %You can use rgb or hsb

newcommandColCell[1]{
  pgfmathparse{#1<50?1:0}  %Threshold for changing the font color into the cells
    ifnumpgfmathresult=0relaxcolor{white}fi
  pgfmathsetmacrocompA{0}      %Component R or H
  pgfmathsetmacrocompB{#1/100} %Component G or S
  pgfmathsetmacrocompC{1}      %Component B or B
  edefx{noexpandcenteringnoexpandcellcolor[colorModel]{compA,compB,compC}}x #1
  } 
newcolumntype{E}{>{collectcellColCell}m{0.4cm}<{endcollectcell}}  %Cell width

begin{document}
newcommanditems{3}   %Number of classes
arrayrulecolor{white} %Table line colors
noindentbegin{tabular}{c*{items}{|E}|}
multicolumn{1}{c}{} & 
multicolumn{1}{c}{A} & 
multicolumn{1}{c}{B} & 
multicolumn{1}{c}{C}  hhline{~*items{|-}|}
A  & 100   & 0  & 10    hhline{~*items{|-}|}
B  & 10   & 80  & 10    hhline{~*items{|-}|}
C  & 30   & 0   & 70    hhline{~*items{|-}|}
end{tabular}

end{document}

I want a table like this image I attached

Here is solution with {NiceTabular} of nicematrix.
documentclass[english]{article}
usepackage{nicematrix}

begin{document}
arrayrulecolor{white}
newcommand{white}{color{white}}

begin{NiceTabular}{c*{3}{|wc{1cm}}}%
 [ cell-space-limits=3pt, code-before = rowcolors{1}{blue!15}{blue!10} rowcolor{blue!50}{1} ]
   & white A    & white B  & white C  
A  & 100         & 0         & 10         
B  & 10          & 80        & 10         
C  & 30          & 0         & 70         
end{NiceTabular}

end{document}

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

Interesting your approach to having a "template style" to apply to tables according the value of the cell.
This answer does not differ significantly from that of F. Pantigny.
Maybe it's closer to the MWE style you posted.

  edefx{noexpandcenteringnoexpandcellcolor[colorModel]{compA,compB,compC}}x #1
  } 
newcolumntype{E}{>{collectcellColCell}m{0.4cm}<{endcollectcell}}  %Cell width

begin{document}
newcommanditems{3}   %Number of classes
arrayrulecolor{white} %Table line colors

noindentbegin{NiceTabular}{cccc}[code-before =  rowcolors{2}{blue!25}{blue!15} columncolor{white}{1}]
    & A     & B   & C     hhline{~*items{|-}|}
A   & 100   & 0   & 10    hhline{~*items{|-}|}
B   & 10    & 80  & 10    hhline{~*items{|-}|}
C   & 30    & 0   & 70    hhline{~*items{|-}|}
end{NiceTabular}

end{document}

Use [code-before =  rowcolors{2}{red!25}{red!15} columncolor{white}{1}] to change the background color to red.
