Material-table: TypeScript types for custom actions are wrong

[vinterdo]

I have custom action on table. Typescript requires function to have signature:
public customAction(event: any, rowData: IRowData[])
It is ok when selection is enabled, but when selection is disabled and action is executed on single row, rowData is just object of this row (not an array). So now i need to do @ts-ignore or my code dont work.

The type for parentChildData is also wrong, as the function returns a single dataset and not an array.
