Need to create a standard table for library, compiler, standard version

[JeffGarland]

Per discussion from July 14 sync meeting we need an example of a table that captures the 'support platform' information -- which will consist of library(libstdc++, libc++) , compiler-version(clang-20, gcc-15), and standard version (c++20, c++23)

Can you provide more information on what's the expected outcome here.

Is this what you're looking for

C++ Version	Support	Note
20	Parital	Constexpr not supported
23	Full
26	Full

or you want like a full permutation table?

C++ Version	Compiler	Standard Library	Support
20	gcc	libstdc++	Except Constexpr
20	gcc	libc++	Except Constexpr
20	llvm	libstdc++	Needs special flags to work fully
20	llvm	libc++	Needs special flags to work fully
23	gcc	libstdc++	Full
23	gcc	libc++	Full
23	llvm	libstdc++	Full
23	llvm	libc++	Full

Full permutation table is very painful to write in markdown.

C++ Version	Tested Compilers	Note
20	gcc12-15, clang19-20, msvc-latest	Constexpr not supported
23-26	gcc14-15, clang19-20, msvc-latest

How about something like this
