Keynote
Add or remove rows and columns in Keynote on iPhone
You can add, delete, and rearrange rows and columns in a table. There are three types of rows and columns:
Body rows and columns contain the table data.
Header rows and columns (if any) appear at the top and left side of the table. They usually have a different background color from the body rows, and they’re typically used to identify what the row or column contains.
Footer rows (if any) appear at the bottom of a table, and they can have a different background color from the body rows.
