//! This example demonstrates using the [attribute macro](https://doc.rust-lang.org/reference/procedural-macros.html#attribute-macros)
//! [`inline`] to expand struct fields to individual columns in a [`Table`] display.
//!
//! * Note that without inlining a struct or enum field, those objects
//!   must implement the [`Display`] trait as they will be represented in
//!   a single column with the value of their [`ToString`] output.
