Upon collapsing and then expanding a column, the header text (e.g., "Trip") does not retain its previous formatting.

Expected Behavior:
On expand, the header should restore a single cell spanning all rows (i.e., rowspan=N) with vertical text formatting like:- Screenshot 2025-07-16 at 11.54.44 AM.png (15.3 KiB) Viewed 36851 times
