Tle longtable package issue with endfirsthead etc. followed by hline

[lahvak]

The longtable commands endhead, endfirsthead, endfoot and endlastfoot append {} after the command, which breaks when there is a hline right after one of these commands. For example

endhead <> hline <> "Some text"

renders as

\endhead{}\hline Some text

which fails with "misplaced \noalign". The correct LaTeX code seems to be

\endhead\hline Some text

Thanks for taking the time to open an issue.

Would never appending {} to \endhead fix this? Do you have a full example I can add to the Examples folder?

[lahvak]

I don't think {} needs to be appended, but either that or a space must be there in case there is text immediately after.

I made an example that I extracted from my application: https://gist.github.com/lahvak/e561467cfac48fb272fb13c48b85bab5

feel free to use it as you see fit. Also, there is an error in the documentation for LongTable:

It says to use the package do

usepackage [] longtable

but it should be longtablep.

I found this which could be related: https://tex.stackexchange.com/questions/463694/misplaced-omit-in-table-and-at-the-end-of-a-command

I guess the real solution is to be smarter about what follows a command. Either {}, a space, or nothing.
