如何在 tabularray 包中使用 \[\]？

我在这里看到了问题和答案这里在答案中，作者使用了colspec = {Q[c,gray9]Q[11.4cm,l]X[c]}?。如何自动设置列的长度。这是我从中复制的代码这里

当我使用$ (2 x+3)\cdot \sqrt{4 x+5}+(6 x+7) \cdot\sqrt{8 x+9}=2. $. 我得到了结果

如果确实需要的话，也可以对方程式进行编号并进行交叉引用。

\SetTblrTemplate{conthead-text}{normal}
\SetTblrTemplate{conthead-text}{normal}

\newcounter{mycnta}
\newcommand{\mycnta}{\stepcounter{mycnta}\arabic{mycnta}}

\newcommand{\hackequation}[1]{%

像这样：

  • tabularray不允许显示方程式，
  • 你需要使用内联数学
  • 当你想模仿 tex 遵循“显示”方程时，你可以写
{Solve the equation\\[1ex]
            $(2 x+3)\cdot \sqrt{4 x+5}+(6 x+7) \cdot\sqrt{8 x+9}=2.$}
