vendor/tabled/examples/iter_table.rs

//! This example demonstrates using [`IterTable`], an [allocation](https://doc.rust-lang.org/nomicon/vec/vec-alloc.html)
//! free [`Table`] alternative that translates an iterator into a display.
//!
//! * Note how [`IterTable`] supports the familiar `.with()` syntax for applying display
//! modifications.
//!
//! * [`IterTable`] supports manual configuration of:
//!     * Record sniffing (default 1000 rows)
//!     * Row cutoff
//!     * Row height
//!     * Column cutoff
//!     * Column width
