脚注不适用于“longtblr”

Question

如何\footnote{}在内部进行工作longtblr？

这是我的 MWE：

\documentclass{article}
\usepackage{tabularray}

\begin{document}

\begin{longtblr}{
      hlines,
      vlines,
      colspec   = {X[1]X[3]},
      rowhead   = 1,
      rowsep    = 0.5ex,
      width     = 0.9\linewidth,
      row{1}    = {font=\bfseries}
    }
    Header       & Second header\\
    First column & Second column\footnote{Hello!}\\
    First column & Second column\\
    First column & Second column\\
    First column & Second column\\
\end{longtblr}

\end{document}

Answer 1

您是否想实现表格注释？像下面的例子一样？

\documentclass{article}
\usepackage{tabularray}

\begin{document}

\begin{longtblr}[
note{a} = {Hello!},
]{
      hlines,
      vlines,
      colspec   = {X[1]X[3]},
      rowhead   = 1,
      rowsep    = 0.5ex,
      width     = 0.9\linewidth,
      row{1}    = {font=\bfseries}
    }
    Header       & Second header\\
    First column & Second column\TblrNote{a}\\
    First column & Second column\\
    First column & Second column\\
    First column & Second column\\
\end{longtblr}

\end{document}

编辑：根据评论，OP 想要在 longtblr 环境中使用实际脚注。然后你可以尝试接受的答案问题。
