Inconsistent underscores false positive?

Ok so this is a fun one. cargo fmt doesn't understand astetics of verticals alas ( https://github.com/rust-lang/rustfmt/issues/4710 ), but with the odd trailing _ you can fool cargo fmt into doing the right thing and making things beautiful:

But clippy's not happy with inconsistent underscores. ( https://rust-lang.github.io/rust-clippy/master/index.html#inconsistent_digit_grouping )

Is there a better solution than a few trailing underscores? (leading underscores are banned) if not, could clippy not complain about trailing underscores please?

Tables come up a lot in programming so it would be nice to have good ways to format them.
