//! Table tests
//!
//! These tests correspond to the table tests in the apple_cloud_notes_parser Ruby implementation:
//! https://github.com/threeplanetssoftware/apple_cloud_notes_parser/blob/master/spec/embedded_objects/tables.rb
//!
//! Tests cover table parsing, reconstruction, row ordering, RTL table support, and output generation.
