Numbers
Intro to tables, charts, and other objects in Numbers for iCloud
An object is any item you add to a spreadsheet. In Numbers for iCloud, charts, tables, text boxes, shapes (including lines), and images are all objects. To add objects to your spreadsheet, click an object button in the toolbar.
After you add an object, you can move it anywhere on the sheet, add content to it, and change its appearance using the controls in the Format sidebar on the right.
You can layer objects on a sheet, resize them, nest them so they appear inline with the text inside a text box or shape, and more.
