PySide6 QTableView with QStandardItemModel Column Insertion (for comparison)
============================================================================

This is a PySide6/Qt reference example showing how to insert columns
using the model/view pattern with QStandardItemModel.

Key Concepts:
- QStandardItemModel: Pre-built model for common use cases
- QTableView: View component that displays the model
- insertColumn(): Add column to model
- setHeaderData(): Set column header text
- Qt.Horizontal: Specify horizontal (column) orientation

Model/View Pattern Benefits:
- Separation of data (model) and presentation (view)
- Multiple views can share one model
- Easier to update data without affecting display

This is the pattern that TTkTable follows, providing similar
flexibility and power in a terminal-based interface.
