Covert existing web page to Lotus Domino XPage

We have an existing web app that was written for an older version of Lotus Domino. I would like to add some functionality to the grid that is difficult to do in the existing technology but may be easier in XPages. I am attaching a picture of the grid. We want to add sorting to the approval column. It is a text field the user will enter. ## Deliverables Here is a picture.
