Add more than XYZ three bottom line labels.

[note286]

Sometimes it is found that only XYZ are not enough. So I want to try whether all 26 letters are supported, although only the last few letters are usually used. I found it defines in \regex_const:Nn \c__tblr_child_name_regex { ^ [X-Z] $ }. If I change X-Z to A-Z, it works such as hline{W}={wd=0.08em}.

I wonder

• Whether this modification will have other bad effects.
• Can A-Z be supported by default in subsequent versions if this modification will not affect the effect of using the current version of the package.
• If the author does not intend to add this directly to subsequent versions. How can I modify X-Z to A-Z in the .tex file without directly modifying the source code of the package?

I am not sure whether it will slow down every tabularray document. How about changing it to U-Z?

[note286]

U-Z is also acceptable. Or add a package option to allow modification.

Done.

Good! Thank you.
