I need to implement the following in the asp.net Gridview. I have the excel sheet as in the image. Based on this image i need to implement data entry application using asp.net gridview.

As you can see in the image from S.NO. 1 TO 5 for every ID Description there are multiple Authors e.g 2,3 or 5. How to implement the same functionality using asp.net gridview so that for every ID Description, user can enter multiple authors while entering the record in the DB design and how to show the records back to gridview as in the excel sheet??
Kindly suggest regarding DB and gridview implementation to handle this?
Thanks
