longtblr 标题随着表格宽度减小而缩小

longtblr 标题随着表格宽度减小而缩小

我发现使用“重新定义的 TblrTemplates”时出现了一些小问题。这个重新定义的模板用于将长 Tblr 标题左对齐。

如果表格的标题足够长，我的格式要求它挂在下一行。如果表格宽度等于文本宽度，表格标题将完美地挂在下一行。当表格宽度不等于文本宽度时，就会出现问题。如您所见，随着表格宽度的减小，标题也会缩小。

我确实尝试过使用 caption 包的解决方案，

\captionsetup{width=1\textwidth}

但它无法工作，因为 longtblr 在其自己的环境中运行。

我做了一些研究并发现了一些答案这里。此解决方案似乎解决了字幕宽度的问题，但由于某种原因，字幕不再挂起。此外，此答案这里解决了字幕挂起的问题，但也缩小了字幕。我尝试将这两种方法结合起来，但失败了。

我没有足够的编程知识来修改 Tabularray 源代码。为了实现表格标题挂在下一行并且宽度与文本宽度相同，我非常需要帮助。任何建议或答案都值得赞赏。
