//! This example demonstrates the flexibility of [`papergrid`] with manual configurations
//! of [`Borders`], [`SpannedConfig`], and column counts with [`IterRecords`].
//!
//! * For an alternative to [`Grid`] and [`SpannedGridDimension`] with
//!   uniform row height and intra-column spans see [`CompactGrid`] and [`CompactGridDimension`].
//! * Note that [`Grid`] supports multiline cells whereas [`CompactGrid`] does not.
//! * Note that [`Dimension`] implementations rely on [`Dimension::estimate()`]
//!   to correctly format outputs, and typically trigger index-out-of-bounds errors otherwise.
