Hi Derek,
Thanks for using Syncfusion product.
The row which appears with * is a an "AddNewRecord" row. To insert a new row, click on the "Add" link, and after giving the values, click on the "insert" button. It will add a new record.
Deletion is same like Editing. You have to simply click on the Delete button to Delete the row.
Please refer the video clip from the below link, which illustrates the process:
