Deleting specific rows in a table

Hi

I have a dynamic table with add and delete buttons for rows. The add button works fine as it just duplicates the table row directly below but I am struggling with the delete button. Using TableReview.Row1.instanceManager.removeInstance(this.parent.index); deletes the first instance in the table and TableReview.Row1.instanceManager.removeInstance(1); deletes the second instance in the table.

I need something that will allow me to delete secific rows (i.e. the one with the delete button on).

Any help would be grately appreciated.
