TTkTable Alignment Example (Method Overloading)

This example demonstrates how to control text alignment in table cells using method overloading.
Each column displays a different alignment type (LEFT, CENTER, RIGHT, JUSTIFIED) by overriding
the displayData() method to return a tuple of (data, alignment).

Key features:
- Custom alignment per column using modulo arithmetic
- Method overloading of headerData() to label alignment types
- Method overloading of displayData() to return (TTkString, Alignment) tuple
- Multi-line cell content demonstrating alignment effects
- Automatic row/column resizing to fit content
