Edit: This question is not related to WebUI, it is more about WinUI. I want the layout changes that I am making in the developer mode to persist. When I switch pages/tabs, the layout changes disappear.

@NK_AP can you check the below options of the pivot table ? I believe setting “Store Entire Tree Layout” to 1 will solve your problem. 

@mohansx “Store Entire Tree Layout” is already set to 1.

@NK_AP, 

On WebUI, you can save the table layout only by moving the indexes around on the pivot table settings.

On WinUI, you can save the table layout in two ways: by End User or by Developer. Just set how you want the layout to be saved, either when the project is being saved (“When being Saved”) or when you close the page (“When page is closing”). Once activated and saved, it will create a new file called ~.DeveloperState if by Developer is activated and ~.UserState if by End User is activated. 

You should set a name for your table also. Does it help? Are you still having problems?
