此crate通过指定一个 Tablefy 特征作为 prettytable 的扩展，将任何（成员实现Display的）结构体转换为 Table 对象。

因此，这意味着 prettytable 是一个依赖项。不添加 prettytable，您将无法使用此crate。

如果您想获取此crate的全部功能（带proc_macro），请务必查看 tablefy_derive!.

未来更新

目前，我考虑对这个crate进行两项主要改进。

• 字段可以被标记来自定义表头名称。
  • 现在已实现！请确保更新 tablefy_derive.
• 字段可以被标记为使用 {:?} 和 {:#?} 而不是 {} 来打印。
