Within Project, you can create a custom Table/View (View > Table > More Tables) that can be based on Screen: Task Sheet. I've gone in and created a new table, called '3-my view' and selected appropriate tables and then created new view based on that table. However, when I switch from '3-my view' to Gantt Chart, the columns I wanted to show still appear. If I hide them in Gantt Chart, they do not appear when changing views. What am I doing wrong?
