如何调整 longtblr（tabularray）中的字体大小？

Question

下面的longtblr表格代码和我的意见有些不同。例如，字体大小，我希望是 10pt，但输出只是将“10pt”放在表格上方，然后继续执行它想要的操作。

\documentclass[a4paper]{article}
\usepackage[top=2cm, bottom=3cm, left=3.5cm, right=3.5cm]{geometry}
\usepackage{tabularray}

\NewTblrTheme{mytable}{
  %\SetTblrStyle{head}{bg=teal7}
  \SetTblrStyle{contfoot-text}{normal}{font=\footnotesize\itshape}
  \SetTblrStyle{caption-sep}{normal}{\enskip\(|\)\enskip}
}

\begin{document}
\begin{longtblr}[
    theme = mytable,
    caption = A very long table,
    font=10pt,
  ]{
    colspec = {X[l,2cm] m{7cm} Q[c] Q[c]}, 
    width = \linewidth,
    rowhead = 1,
    row{1} = {teal7},
  }
      \hline[1.5pt]
      column 1 & column 2 & column 3 & column 4 \\
      \hline
      row & some relatively long description so that the other entries can showboat their floatiness & row & \SetCell[r=2]{c} rows centred in two \\
      row & less showboating, maybe even no showboating & row & \\
      row & some relatively long description so that the other entries can showboat their floatiness & row & \SetCell[r=2]{c} rows \\
      row & less showboating, maybe even no showboating & row & \\
      row & some relatively long description so that the other entries can showboat their floatiness & row & \SetCell[r=2]{c} rows \\

      row & less showboating, maybe even no showboating & row & \\
\end{longtblr}
\end{document}
}

有什么想法吗？

编辑以减少示例中的错误。但是，我似乎误解了软件包文档。在我看来，颜色和字体命令似乎已随软件包加载，而第一位评论者告诉我要修复这些问题。此外，似乎并非如此\linewidth。

Answer 2

我稍微简化了代码，并彻底清除了错误。如果您要自定义longtblr，则应阅读文档，主要是与相关的部分longtblr。一开始可能不太容易理解，但一旦你了解了主题和自定义样式的工作原理，就很容易理解了。

我不明白字体大小的问题，因为字体大小10pt是常规文档中的默认字体大小。但是，即使文档设置为（见示例），也可以为表格设置特定的字体大小12pt。确保将表格放在\fontsize组中，这样它只会影响表格。

这是你可以借鉴的有效代码。我添加了几段虚拟文本，以便将表格与常规内容进行比较。
