Hi @C. Peter Datz & @markkrebs
In Table View, you can now un-hide a set group of columns instead of only having the option to un-hide all columns (which is also still available).
The way to do this is to double-click on the hidden column(s) indicator! This will unfurl all of those hidden columns without expanding open the entire sheet.
You are correct, this is not a choice to individually un-hide each specific column based on title. For this request, please continue to vote on and leave your comments on the related Product Idea where updates will be posted: Hidden Columns List
Cheers,
Genevieve
