What problem does it solve? Canvas Power Apps has no native editable grid control, so users who need to edit many rows at once are stuck with slow form-per-row screens or read-only data tables. This Skill provides the complete pattern for building an editable table: a staging collection bound to a gallery with per-row inputs, add/insert/delete row operations, and a single bulk save back to the data source. ## Core Features & Use Cases - Staging-collection grid design: Load a delegable working copy into a collection, bind the gallery to it, and let users edit freely without per-keystroke network calls. - Row lifecycle management: Add rows with client-side TempIds, delete rows with a tracked colDeletes collection, and reconcile everything on save. - Bulk save with correct Patch semantics: Branch on ID > 0 to merge updates onto existing records and inserts onto Defaults(Source), avoiding duplicate rows and silent no-ops. - Use Case: Build a timesheet grid where employees enter a week of hours across multiple project rows, then save all entries to a SharePoint list with one button. ## Quick Start Ask the AI to build an editable grid screen in a canvas Power App that stages SharePoint list rows in a collection and saves all edits with one bulk Patch.
