I made the following changes to your code:
1. Changed the label of the delete button to "Delete" as requested.
2. Modified the action of the delete button to remove the entire row associated with it.
3. Fixed compilation errors and added missing imports.
4. Improved code formatting and corrected some syntax issues.
