Add and print comments in Numbers on iPhone
You can add comments to text, objects, charts, table cells, and sheets. A small square appears next to text (which is also highlighted) to indicate a comment is attached. Comments attached to shapes are also indicated by a small square. Comments in table cells are indicated by a triangle in the corner of the cell. When you don’t want comments to be visible, you can hide them, and you can print a spreadsheet with or without comments.
When multiple people are working on a spreadsheet, each person’s comments appear in a unique color and include their author name. Anyone can reply to a comment, which is especially useful if you’re collaborating—you can add a comment, then with back-and-forth replies have a conversation in real time.
Note: Comments aren’t visible in printed spreadsheets unless you select that printing option.
