Using QStyledItemDelegate, it ensures that only numeric values are entered into designated columns of the table, maintaining data integrity while allowing flexibility for other data types in different columns.
This version introduces:
- Selective Table Validation: Implements custom delegates with
QStyledItemDelegateto enforce numeric-only input for specific columns that require numeric data, while other columns can accept different types of data. - User Input Error Handling: Provides immediate feedback for invalid entries in numeric columns, helping users correct data entry errors efficiently.
