//! This example demonstrates using the [attribute macro](https://doc.rust-lang.org/reference/procedural-macros.html#attribute-macros)
//! [`skip`] to omit specific fields from becoming columns in a [`Table`] display.
//!
//! * Note how [`skip`] annoys [clippy](https://doc.rust-lang.org/clippy/) with `dead_code`
//! warnings. This can be addressed with compiler overrides like `#[allow(dead_code)]`.
