URL: https://github.com/apache/superset/pull/38276#issuecomment-3989976135
## **Sequence Diagram**
This PR ensures column IDs derived from empty-string dimensions are always
strings and protects the table mapping logic from non-string IDs to avoid a
TypeError when calling .includes('.'). The diagram shows the main successful
path from column construction to table rendering with the two defensive changes.
```mermaid
sequenceDiagram
participant ExploreUI as Explore (Results)
participant useTableColumns as useTableColumns (DataTableControl)
participant TableCollection as TableCollection.mapColumns
participant AntTable as Ant Design Table
ExploreUI->>useTableColumns: Build table columns from query results
note right of useTableColumns: If column key is empty, use String(index)
as id
useTableColumns->>TableCollection: Pass columns (ids guaranteed string)
note right of TableCollection: Guard: only call .includes('.') when
typeof id === 'string'
TableCollection->>AntTable: Map columns/data and render table
AntTable-->>ExploreUI: Rendered Results table (no TypeError)
```
