I just built a C++ formatter that does this (owned by my employee, unfortunately). There's really only two formatting objects: tab-aligned tables, and single line rows. Both objects also support a right-floating column/tab aligned "//" comment.

Both objects desugar to a sequence of segments (lines).

The result is that you can freely mix expression/assignment blocks & statements. Things like switch-case blocks & macro tables are suddenly trivial to format in 2d.

Because comments are handled as right floating, all comments nicely align.

I vibe coded the base layer in an hour. I'm using with autogenerated code, so output is manually coded based on my input. The tricky bit would be "discovering" tables & block. I'd jus use a combo of an LSP and direct observation of sequential statements.

You built it, but your employee owns it? That sounds highly unusual.
