2 多个不同列数的panel合并成一个长表格

多谢回复，已经在问题中添加了代码。

@u134749 你好，longtblr应该是所有列的列数都相同的效果，你的\tapa,\tapb等子表的列数不完全相同，你需要给定如果需要一个跨页的长表格，第一个panel的几列如何垂直对应到第二个panel，如下图：

一个标准版的longtblr应该如下所示（具有明显的方便对齐的align锚点）：

另外，建议你思考：真的需要要把5个列数（或者说列格式）如此不统一的表格纵向堆叠成一个长表格吗？

@u70550 再次感谢您的回复。目前是有这个需求，是否能用别的方法实现？比如独立生成多个panel，再外面嵌套一层将其合并？

@u134749 我觉得要实现你说的，它可以是5个longtblr,这样可以做到每个表如果跨页就会重复表头。

嗯嗯。我试试，谢谢啦~

@u134749 你想重复显示的表头指的是 Panel那一行还是指标的那一行呢？ 另外你是否在交流群(91940767)内？
如果想重复Panel那一行，可以用rowhead=1;
如果想重复Panel和指标共两行，可以用rowhead=2;
如果只想重复指标的那一行，可能需要让Panel不在第一行

我本来想修改原回复的，但是已经采纳乐，我对tabularray宏包并不那么熟悉...所以我并没有解决你的问题，下面是我的一个不那么好的解答吧...不那么好的原因是：
一是没有把5个panel的longtblr合并为一个浮动体table（这个也说明了我这个思路不够好）;
二是觉得代码还有很多可以复用以及利用样式更快捷实现的地方;

几处需要注意的地方：

1. tabularray宏包提供了\UseTblrLibrary{booktabs}方便直接插入三线表而不用手动指定;
2. 使用presep=5pt,postsep=0pt,让5个longtblr更紧凑
3. 采用临时修改default的方法，并暂时把Panelxxx作为caption(其实我觉得这不太好，但暂时没想到其他好办法...)

\DefTblrTemplate{caption-tag}{default}{}
\DefTblrTemplate{caption-sep}{default}{}

下面的MWE并不elegant...

也希望有大神帮我改改上面的代码？
and：对于多个列格式完全不相同的有跨页需求的表格，如何排版才能让他们即跨页方便，又可以直接纵向堆叠并使用table实现浮动呢？

@u70550 这里的"浮动"措辞有误，感谢@u19850 指出。
