Spreadsheet Cell Comments is the Google Sheets style cell review surface: a Q3 marketing budget grid where four flagged cells carry a corner comment marker, paired with a side rail that opens the full thread for the selected cell. C4 is active, so Priya Nair explains the freelance retainer reclass and Jordan Lee asks her to note it on the Finance tab. Below the thread, a compact list shows the other commented cells: Jordan Lee on E2, Maya Chen on B6, and Avery Stone on D7, each with its ref, author, and note snippet.
Cells and threads are typed arrays, and a flagged set plus a single active ref decide which cells wear a marker and which one lights up alongside its rail thread. The selected cell and its open thread share the same highlight, keeping the render branch simple. The footer note tells users markers survive sorting and filtering and that resolving a thread clears the marker for everyone on the sheet.
Reach for this block as the cell comment layer of any spreadsheet or data grid tool, wired to your comment endpoint and the currently selected cell. Bind Reply to your thread append call and Resolve to your thread-close mutation.

Tip: the paired highlight between a flagged cell and its open thread is what keeps the grid readable, so let the active ref drive both and reviewers never lose the cell in question.
