保留第一行两列，其余单列宽并换行

Question

我试图在顶行保留两列，并使其余的单列具有自动宽度扩展。但是，我不知道该怎么做。我阅读了文档，但细节太多，我无法理解。

代码：

\documentclass[a4paper,11pt]{article}

\usepackage{tabularx}
\usepackage{tabularray}
\usepackage{float}

\begin{document}
\begin{table}[ht]
    \begin{tblr}{width=\textwidth,
            colspec={X[l]  X[r]},
            hline{1,3} = {solid},
        }
        \text{Lorem Ipsum} & \text{Ipsum Lorem}\\
        It is easy with "tabularray" package to set row fonts. And you can change the environment from "tblr" to "longtblr" to get a long table. \\
    \end{tblr}
\end{table}
\end{document}
