Cannot add _RowNumber columns after changing to the new column order editor

[イルカのえっちゃん]

SHOW in the _RowNumber column is checked in the Target table.

When trying to add a _RowNumber column from the Add button in the Column Order manual, it does not appear.

Check if the column is visible in the table configuration and, if it is a slice, check if it is added to your slice.

The SHOW of the column is switched on.
Views are based on tables, not slices.

If you are in the new column editor, you should try this.
When I heard about this case from a third party, I didn't believe it, but when I tried it, it was indeed the case.

I have requested this case from the support team.

What is the view type where you are trying to add it?

View type is a table type.
