New rows can be added to a DataTable using the row.add() API method. Simply call the API function with the data for the new row (be it an array or object). Multiple rows can be added using the rows.add() method (note the plural). Data can likewise be updated with the row().data() and row().remove() methods.

Note that in order to see the new row in the table you must call the draw() method, which is easily done through the chaining that the DataTables API employs.

This example shows a single row being added each time the button below is clicked upon.

The Editor extension adds full table editing controls to a DataTable, including creating, editing and deleting rows.
