You can show or hide columns in a list or library as an alternative to deleting them. When you hide a column, it doesn't affect the column or the data in the column, as it would if you deleted it. To re-use the column, you can just show it again.
Note
To show or hide a column in a list or library, you must at least be a member of the default designer group.
You can also add, change, or delete columns in a list or library, as well as create or delete a list from a page or site. For more information about managing lists or libraries with many items, see Manage large lists and libraries.
Show or hide a column in a list or library
Go to the list or library where you want to show or hide columns.
To just hide a single column, at the top of any column, select the down arrow
, then select Column Settings > Hide this column.
To unhide(show) the hidden columns, and hide more columns, at the top of any column, select the down arrow
, then select Column Settings > Show/hide columns.
In the Edit view columns pane, check (to show) or uncheck (to hide) the box for the column or columns as needed.
Note
If you want to rearrange the order of the columns, either drag and drop the column name, or select the up or down arrow next to the column name as preferred.
When you're finished, select Apply to save the view.
Note
Both "Hide a column" and "Apply" on the Edit view columns panel autosave the changes to the view directly.
