Repeat row specification in longtblr

[celdorwow]

Hello,

I have a long table created in longtblr env., which is working all right but I 'd have a small request.
Currently, rowhead and rowfoot work such that row specifications as well as row content are repeated across multiple pages.

I was wondering if it's possible to request that only row specifications would be repeated. The content would follow the table content and would be populated accordingly.

For instance in the table below on every consecutive page (or column in twocolumn format) I would like:

• every second row (after header) to be typeset in Red and has abovesep set to 3pt, as well as
• every second to the last row to be typeset in Green and has belowsep set to 3pt.

I was wondering is such thing is possible.

Thanks

Here's MWE:

It is impossible in tabularray. For white spaces, you may try to add one empty row of 3pt height to each of rowhead and rowfoot. For foreground colors. it may be possible if there are some hooks for page tables of longtblr in the future.
