Currently, in the Portal 2 table, changes made to data source records are indicated as updated (with a green color and pencil icon), but these changes are not actually saved until the 'Update' button is clicked. This setup risks data loss if the user performs an action that refreshes the table without first hitting 'Update', and currently, there is no warning to the user that their changes will be discarded.

Proposed solution is to either Implement an auto-save functionality that automatically saves changes made to the table immediately after a value is altered. This will ensure that all changes are preserved without requiring users to manually click the 'Update' button. Alternatively, or additionally, provide a clear warning/notification to users when they attempt to navigate away from the page or perform any action that would result in losing unsaved changes. This alert would prompt users to save their changes before proceeding.

Either solution will significantly enhance data security and user experience by preventing accidental data loss.
