In the OC Group View, when we click on the group name and see members tab (example, user tag 2), we can widen User Tag 2, but the width automatically reverts before we can see the field contents.
UIM 20.4.x/ 23.4.x
In Groups view we are not persisting the table's column width modification. This functionality is available only in Alarms view table.
In groups view, the data will get refreshed in every 30 seconds. During that refresh all computer systems of that group will get updated with the latest values and the table also will get reset to it's original settings.
This is not a bug and is working as expected.
If customer wants to persist the table's column width in Groups view as well, then they can raise an idea in the community.
