//! This example demonstrates using the [attribute macro](https://doc.rust-lang.org/reference/procedural-macros.html#attribute-macros)
//! [`rename_all`] to apply table-wide header formatting in a [`Table`] display.
//!
//! * Supported formatting rules include:
//! * 'camelCase'
//! * 'kabab-case'
//! * 'PascalCase'
//! * 'SCREAMING_SNAKE_CASE'
//! * 'snake_case'
//! * 'lowercase'
//! * 'UPPERCASE'
//! * 'verbatim'
