Reorder rows in an ADF table

Reorder rows in an ADF table. As shown in the images below, applying the code in this post will allow you to re-arrange rows within a table using "up and down" buttons Its simply and change rank attribute value of swiped rows and change in the indexing of the iterator. 

Selecting a row and move it to a step up or down ,then will  show it in its new position within the table

and you may commit later

Note that reordering the rows in the table will only have an effect to the DCIteratorBinding (more precise, its an effect to the RowSetIterator it decorates) in the Pagedef file.
