Can't set table width correctly with NiceTabular* environment in NiceMatrix package

Question

The sample codes:

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\noindent
\begin{NiceTabular*}{\textwidth}{XX}[hvlines]
    X & X \\
\end{NiceTabular*}
\end{document}

The output:

I replace {XX} by {CC}, and the output:

Answer 1

The latest version of nicematrix (6.0 of 2021-08-10) provides an environment {NiceTabularX} similar to the classical environment {tabularx} of the package tabularx.

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\noindent
\begin{NiceTabularX}{\textwidth}{XX}[hvlines]
    X & X \\
\end{NiceTabularX}
\end{document}

Answer 2

{NiceTabular*} is not equivalent to {tabularx} (of the eponymous package) but to the standard {tabular*} (certainly less efficient). So, there is no X column in {NiceTabular*}.

\documentclass{article}
\setlength{\parindent}{0pt}
\usepackage{nicematrix}
\usepackage{lipsum}

\begin{document}

\lipsum[1]

\begin{NiceTabular*}{\linewidth}{@{\extracolsep{\fill}}ccccc}
one & two & three & four & five \\
six & seven & eight & nine & ten \\
eleven & twelve & thirteen & fourteen & fifteen
\end{NiceTabular*}

\end{document}
