| //! This example demonstrates using the [attribute macro](https://doc.rust-lang.org/reference/procedural-macros.html#attribute-macros) |
| //! [`skip`] to omit specific fields from becoming columns in a [`Table`] display. |
| //! |
| //! * Note how [`skip`] annoys [clippy](https://doc.rust-lang.org/clippy/) with `dead_code` |
| //! warnings. This can be addressed with compiler overrides like `#[allow(dead_code)]`. |
