oxidize-pdf 4.2.2

//! Example demonstrating automatic text truncation in table cells
//!
//! This example shows how the text truncation system works:
//! - Text that exceeds cell width is automatically truncated with "..."
//! - Different alignment options work correctly with truncated text
//! - Demonstrates the solution for overlapping text in narrow cells
