I have this table using `tabularray`
```
\documentclass[12pt,a4paper]{article}
\usepackage{hyperref}
\usepackage{fouriernc}
\usepackage[left=2cm, right=2cm, top=2cm, bottom=2cm]{geometry}
\usepackage{mathtools}
\usepackage[most]{tcolorbox}
\usepackage{systeme}
\usepackage{mhchem}
\usepackage{float}
\usepackage{enumitem}
\usepackage{tasks}
\usepackage{tabularray}
\UseTblrLibrary{booktabs,
counter,
diagbox,
siunitx,
varwidth}
\usepackage{ninecolors}
\newcounter{mycnta}
\begin{document}
\begin{table}[H]
\centering
\begin{tblr}{colspec = {@{}cll@{}},
hlines, vlines,cells={mode=dmath},
row{1}={mode=text,c,blue9}
}
Produce & supply function & demand function \\
A & Q_{S_A}=4 x-y-z-5 & Q_{D_A}=-2 x+y+z+9 \\
B & Q_{S_B}=-x+4 y-z-5 & Q_{D_B}=x-2 y+z+3 \\
C & Q_{S_C}=-x-y+4 z-1 & Q_{D_C}=x+y-2 z-1 \\
\end{tblr}
\end{table}
\end{document}
```
How can I repair it?

With `@{}` you remove the padding on one side of the cell. This will a) make the centred text look asymmetric because the padding at one side is missing and b) makes the content of the cell (like `9`) very close to the cell border. Both problems can be solved by not using `@{}`:
