在threeparttable常规tabular环境中，我能够通过添加自定义注释来实现格式设置（左对齐，跨越整个表格宽度，没有标签，同时保持表格脚注缩进）外部环境tablenotes（但在threeparttable环境内，请参见下面的代码和屏幕截图中的表 1）。
现在我尝试使用组合threeparttablex+复制此格式longtable，但我很难达到相同的效果。到目前为止，唯一可行的选择似乎是将其添加到下面insertTableNotes。但这样，自定义注释将被视为增加表格宽度的普通行，而不是被换行：
是否有人有解决方案，可以复制表 1 的格式，而无需手动指定表宽度？
笔记：\note我不使用该命令或flushleft选项的原因threeparttablex是：1）我希望能够传递没有标签的注释；2）flushleft不能完美地左对齐文本。

这是使用该包的解决方案tabularray。
\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{booktabs}
\NewTblrTheme{MyTheme}{

\UseTblrTemplate{remark-tag}{MyTag}%
\UseTblrTemplate{remark-sep}{MyTag}%
\UseTblrTemplate{remark-text}{MyTag}

\SetTblrTemplate{remark}{MyTmp}

\begin{document}

注意：我使用默认TblrNote命令插入常用表格注释。为了添加自定义注释，我更改了模板remark并将其作为新主题插入。
