cell: does not accept letters in cell list

[CarLaTeX]

Please look at this MWE:

\documentclass{article}
\usepackage{xcolor} 
\usepackage{tabularray}

\begin{document}
	This works:
	
	\begin{tblr}{colspec={ccc},
			cell{{1}{2},{1}{3}} = {bg=blue},
			cell{{3}{1},{2}{1}} = {bg=red}
		}
		1 & 2 & 3  \\
		2 & 2 & 3  \\
		3 & 2 & 3  \\
	\end{tblr}
	
	This does not:
	
	\begin{tblr}{colspec={ccc},
			cell{{1}{2},{1}{Z}} = {bg=blue},
			cell{{Z}{1},{2}{1}} = {bg=red}
		}
		1 & 2 & 3  \\
		2 & 2 & 3  \\
		3 & 2 & 3  \\
	\end{tblr}
\end{document}

The first table, with cell row and column numbers, works.
The second table, with Z for last row or column, gives the error: ! Missing number, treated as zero.

Thank you, bye! Carla

You can not use letters in two dimensional indexes (which needs to be documented), but will be able to use negative indexes in them with a future release (see issue #581).
