```

## Parameters

- `id`: The identifier to associate with a column.

## Discussion

Discussion This is required to allow user customization of a specific table column, in addition to the table as a whole being provided a binding to a TableColumnCustomization. The identifier needs to be stable, including across app version updates, since it is used to persist the user customization.
