Adding / Del Rows in middle of table

Hi

A general question in adding rows in a table where rows are already added dynamically

How to add a row in the middle of a table when the table has the capability of add rows dynamically.

So each row will have the add /del row icon. If the user clicks the add button displayed on a row, it should add a row immediately below that row. Similarly delete row as well

Kindly help on the above
