Different header rows in different pages of a long table

Question

I came across this question which wants no header rows on the last page. While trying to find a way for that I was wondering if it's possible to have different header rows on different pages automatically. An MWE is given with the tabularray package but it's not necessary to use this package for a solution. So, is it possible to have different header rows on different pages?

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabularray}
\begin{document}
\begin{longtblr}[
 caption = {A Long Long Long Long Long Long Long Table},
 entry = {Short Caption},
 label = {tblr:test},
]{
 colspec = {XXX}, width = 0.85\linewidth,
 rowhead = 2, rowfoot = 1,
 row{odd} = {gray9}, row{even} = {brown9},
 row{1-2} = {purple7}, row{Z} = {blue7},
}

note you have tagged this longtable but longtable and tabulararry do not share any code so any solution for one will not apply to the other, you may want to tag both packages and make your title clearer that you refer to a generic "long table" not specifically longtable — David Carlisle, Dec 04 '21 at 15:59
@DavidCarlisle Thanks, edited the title. Please add the appropriate tag or remove the inappropriate one. Solution using any package is acceptable and I am not sure which tag to add in that case (I thought longtable tag wasn't related to any package, so I added that). — Imran, Dec 04 '21 at 16:08
if you hover over the longtable tag below your question you will see it references the package there is this for longtable https://tex.stackexchange.com/questions/263597/change-endhead-in-the-middle-of-a-longtable/263602#263602 — David Carlisle, Dec 04 '21 at 16:22
The row head and foot are saved in boxes at the beginning of the tblr construction, and so they cannot be changed mid-table. You could try to put this information in the table head instead, (as a mini tblr in the capcont template), but it would probably be difficult to align it with the main table. — Pieter van Oostrum, Dec 04 '21 at 19:26

The row head and foot are saved in boxes at the beginning of the tblr construction, and so they cannot be changed mid-table. You could try to put this information in the table head instead, and then you can differentiate between first, middle and last head. These are also put in boxes, so you can only differentiate between the first end last one, and all the intermediate ones (the latter ones will be all the same).

Here is an example of how this could be done. I have used the capcont template, which applies to all headers after the first one. If you want to differentiate between the middle and the last headers, you should use the middlehead and lasthead templates instead.

It could use some improvement in the spacing. If you use different colspecs the header might not align with the rest of the table.

How can one remove the small white gap between the purple row 2 with the text Head-2 and the continued table? — Hotschke, Aug 21 '22 at 14:40
I have done this. I was hoping for a cleaner way by not introducing the whitespace in the first place. — Hotschke, Aug 21 '22 at 15:15
I found out what caused it and I edited the solution: (1)remove the \hline before \end{tabular} ; (2) remove the \par at the end of the template. I also replaced \linewidth by \textwidth. — Pieter van Oostrum, Aug 21 '22 at 20:38
Unfortunately, it did not work for me. I will go with \vspace{-6pt} which is the value from footsep. — Hotschke, Aug 22 '22 at 07:09
