on the SharePoint site how can i move the columns from right to left. i have 50 columns i want to move from one column which is at 50th to 10th column. Do i need to go column settings and move right to left or is there any way which i can move directly from 50th to 10th column.

Answer 1

I cannot reproduce this issue in my environment. Please check as following:

1. How many items do you have in this list? How many people, lookup, and managed metadata columns do you have in the All Items view?
   Do you have any trouble creating a new list view by selecting a view type under "Choose a view type", for example, “Standard View”? If you are managing a large list or having too many special columns in the All Items view, it might cause the list view threshold error while creating a new list view following this process. Try creating a new list view from "Choose a view type" and see if it works.
2. To adjust column order in a list view, please select the view you want to modify via List Settings > Views, find the 50th column under Columns and then change the number to 10 under "Position from Left".
   Reference: Change the column order in a list or library.

If you are on SharePoint Online submit a support ticket to either your IT helpdesk or Microsoft Support via the admin portal.

If you are using an on-premise SharePoint server you are going to have your IT helpdesk check the ULS log with that Correlation ID.

How many lookup columns do you have in that view? With 50 columns you could be over the allowed default limit.
