Add, edit, or delete categories in Numbers on iPad
You can use categories to organize the data in your table. For example, if you have a spreadsheet that tracks shirt sales, you could create a category that groups sales by month or by salesperson.
There are two ways to create a category in Numbers: choose a source column of data that you want to group, or manually select rows that you want to group. Choosing a source column is best when your table already contains the data you want to group. Manually selecting rows works best when the data you want to group isn’t in the table. For example, you might have a table that’s a roster of students in your class. If the students created their own groups for a science project, you could organize the roster by these groups without adding a “science project” column to the table.
A table can have one main category and up to four subcategories to create a hierarchy for your data. You can change this hierarchy, rename or delete categories, and more.
