Color gradient in the table

Question

How can I make a color gradient in a table from the first row to the last row (from top to bottom)?

\documentclass[]{article}
\usepackage{tabularray}
\usepackage{xcolor}
\begin{document}
\begin{tblr}{
  width = \linewidth,
  colspec = {Q[165]Q[165]Q[165]Q[165]},
  cells = {c},
  row{1} = {blue!50},
  row{2} = {cyan!50},
  hlines,
  vlines}
 a & B & C & D \
one & two & three & noone
\end{tblr}
\end{document}

Here is an example with {NiceTabular} of nicematrix with a row by row color gradient (you need several compilations).

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{c}
\CodeBefore
   \definecolorseries{BlueWhite}{rgb}{last}{blue}{white}
   \resetcolorseries[\value{iRow}]{BlueWhite}
   \rowlistcolors{1}{BlueWhite!!+}
\Body
Mathilde \
Pierre \
Paul \
Amélie \
Jacques \
Antoine \
Stéphanie \
\end{NiceTabular}
\end{document}

Here is an example with a continuous gradient (Tikz must be loaded).

\documentclass{article}
\usepackage{nicematrix,tikz}
\begin{document}
\begin{NiceTabular}{c}[color-inside]
\Block[tikz = {top color=blue, bottom color=white}]{-}{}
Mathilde \
Pierre \
Paul \
Amélie \
Jacques \
Antoine \
Stéphanie \
\end{NiceTabular}
\end{document}

In both cases, the instructions automatically take into account the number of row and columns of the tabular.
