vendor/tabled/examples/colorization.rs

//! This example demonstrates using the [`Color`] [setting](tabled::settings) to
//! stylize text, backgrounds, and borders.
//!
//! * 🚩 This example requires the `color` feature.
//!
//! * Note how [`Format::content()`] is used to break out [`CellOption`]
//! specifications. This is helpful for organizing extensive [`Table`] configurations.
