Why does cellcolor not work here?

Question

The code is from answer of my previous question here. I'm trying to color a cell of a table as the code here.

\documentclass[journal]{IEEEtran}
\usepackage{mathtools}
\usepackage{tabularray}
\UseTblrLibrary{booktabs}
\usepackage[table]{xcolor}
\begin{document}
  \begin{table}[!t]
    \centering
    \caption{Adjacency Matrix}
    \label{tab:Adjacency Matrix}
    \begin{tblr}{
            colspec={*6{c}},
            vline{1} = {2-Z}{0.8pt},
            vline{2,Z} = {0.8pt},
            vline{3-Y} = {0.3pt},
            hline{1} = {2-Z}{0.8pt},
            hline{2,Z} = {0.8pt},
            hline{3-Y} = {0.3pt},
            row{1} = {mode=math},
            column{1} = {mode=math},
        }
        & V_1 &  V_2 & V_3 & V_4 & V_5 \
        V_1 & \cellcolor{gray!25}1 & 1 & 0 & 0 & 1 \
        V_2 & 1 & 0 & 1 & 0 & 1 \
        V_3 & 0 & 1 & 0 & 1 & 0 \
        V_4 & 0 & 0 & 1 & 0 & 1 \
        V_5 & 1 & 1 & 0 & 1 & 0 \
    \end{tblr}
  \end{table}
\end{document}

tabularay provides two ways to colourise cells: either in a table definition via cell{rowA-rowB}{colX-colY} or directly in the "data" via \SetCell{...} as @Zarko answered. If it's just one cell, it doesn't matter. But if you have a range of cells to colourise, I'd use the former way. You can change both foreground and background of cells. Try to add the following to the table definition: cell{1}{2-Z} = {bg=blue,fg=white}, cell{2-Z}{1} = {bg=black!50!green,fg=white},. — Celdor, Aug 18 '22 at 18:11

Package tabularray has own mechanism for coloring cells. Try the following:

\documentclass[journal]{IEEEtran}
\usepackage{xcolor}
\usepackage{tabularray}
\UseTblrLibrary{booktabs}
\NewTableCommand\SCC[1]{\SetCell{bg=#1}}  % <--- shortcut
\begin{document}
  \begin{table}[!t]
    \centering
    \caption{Adjacency Matrix}
    \label{tab:Adjacency Matrix}
    \begin{tblr}{
            colspec={*6{c}},
            vline{1} = {2-Z}{0.8pt},
            vline{2,Z} = {0.8pt},
            vline{3-Y} = {0.3pt},
            hline{1} = {2-Z}{0.8pt},
            hline{2,Z} = {0.8pt},
            hline{3-Y} = {0.3pt},
            row{1} = {mode=math},
            column{1} = {mode=math},
        }
        & V_1 &  V_2 & V_3 & V_4 & V_5 \
        V_1 & \SCC{gray!25}1 & 1 & 0 & 0 & 1 \
        V_2 & 1 & 0 & 1 & 0 & 1 \
        V_3 & 0 & 1 & 0 & 1 & 0 \
        V_4 & 0 & 0 & 1 & 0 & 1 \
        V_5 & 1 & 1 & 0 & 1 & 0 \
    \end{tblr}
  \end{table}
\end{document}

Addendum: you also an color cel(s) in table preamble:

\`[journal]{IEEEtran}
\usepackage{xcolor}
\usepackage{tabularray}
\UseTblrLibrary{booktabs}
\NewTableCommand\SCC[1]{\SetCell{bg=#1}}
\begin{document}
  \begin{table}[!t]
    \centering
    \caption{Adjacency Matrix}
    \label{tab:Adjacency Matrix}
    \begin{tblr}{
            colspec={*6{c}},
            vline{1} = {2-Z}{0.8pt},
            vline{2,Z} = {0.8pt},
            vline{3-Y} = {0.3pt},
            hline{1} = {2-Z}{0.8pt},
            hline{2,Z} = {0.8pt},
            hline{3-Y} = {0.3pt},
            row{1} = {mode=math},
            column{1} = {mode=math},
            cell{2}{2}={bg=gray!9}  % <---
        }
        & V_1 &  V_2 & V_3 & V_4 & V_5 \
        V_1 &   & 1 & 0 & 0 & 1 \
        V_2 & 1 & 0 & 1 & 0 & 1 \
        V_3 & 0 & 1 & 0 & 1 & 0 \
        V_4 & 0 & 0 & 1 & 0 & 1 \
        V_5 & 1 & 1 & 0 & 1 & 0 \
    \end{tblr}
  \end{table}
\end{document}

result is the same as before.

Why does cellcolor not work here?
