我需要一些快速帮助来弄清楚如何在longtable我使用的地方将文本居中bigdelim/multirow。

例如，我希望文本“亨利定律常数”位于两个花括号之间的中心。
答案1
- 对于 { 引入了新列
r - 对于化学公式来说，严格使用宏
\ce{...}（即使在下标中） - 对于单位使用
siunitx包 - 第二列的文本未居中，我认为左对齐更好

附录： 对于第二列中垂直和水平居中的文本，引入一个新列并将文本移动到花括号中间的行：

你至少需要 5.10 (2021-02-05) 版本nicematrix。如果你使用 Overleaf，你可以上传最新版本的文件nicematrix.sty。如果你使用 Overleaf，你可以在项目的目录中SVN 服务器来自 TeXLive 的网站。
您需要多次编译（因为nicematrix使用 PGF/Tikz 节点）。
