Get some clear (very important) spray adhesive and use to "restick" the fabric on the plastic backing. The A pillar can be removed without tools. You will wish you knew how to do this for the "moon roof" on your first vehicle. Key is to spray the adhesive and hold back the fabric until the glue gets tacky. Just follow directions, this is an easy one.
I did this on mine (same spot) after my 16 year old did the research, dragged me to Lowes and fixed the roof on his new to him 1999 jeep Cherokee. The section he replaced was over a square foot in size and it looks like new and you cannot pick out where he did the repair.
Cost, $6 and 5 minutes.
Good luck
