Add or remove table rows and columns in Pages on iPad
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.
Note: The tasks below apply to a table you add to the page using 
in the toolbar. They don’t apply to a page you formatted into columns.
Add or remove table rows and columns

in the top-right corner of the table to add or delete columns.Change the number of rows or columns in the table: Select the table, then tap

You may not be able to delete a row or column if all its cells aren’t empty.
You can also copy rows and columns from a table in another document, or from Keynote or Numbers.
Add or remove header rows and columns
Adding header rows, header columns, and footer rows converts existing rows and columns into headers or footers. For example, if you have data in the first row of a table and you add a header row, the first row is converted to a header row that contains the same data. Data in header cells isn’t used in calculations.
