vendor/tabled/examples/builder_index.rs

//! This example demonstrates evolving the standard [`Builder`] to an [`IndexBuilder`],
//! and then manipulating the constructing table with a newly prepended index column.
//!
//! * An [`IndexBuilder`] is capable of several useful manipulations, including:
//!     * Giving the new index column a name
//!     * Transposing the index column around a table
//!     * Choosing a location for the new index column besides 0; the default
//!
//! * Note that like with any builder pattern the [`IndexBuilder::build()`] function
//! is necessary to produce a displayable [`Table`].
