TTkTable Clipboard Operations Example
======================================

This example demonstrates table clipboard functionality and complex data types.

Key Features:
- Clipboard operations (copy/paste) with Ctrl+C/Ctrl+Z signals enabled
- Mixed data types in cells:
  * Hex numbers (formatted strings)
  * TTkString with colors
  * Boolean values
  * TTkCellListType (dropdown lists)
  * Custom Enum types
  * datetime.time objects
  * datetime.date objects
  * datetime.datetime objects
- Random data generation for dates and times
- Signal mask configuration for clipboard shortcuts

Usage:
- Select cells and press Ctrl+C to copy
- Use Ctrl+Z for undo (if enabled in application)

This example shows how TTkTable handles various Python data types
and provides built-in clipboard support.
