PBI - merge合并多表时，如何添加列显示表名？

POWER BI  - 需要进入advanced editor修改：

    Source = Table.Combine({Table.AddColumn(#"query A", "source query", each "query A")
                            , Table.AddColumn(#"query B", "source query", each "query B")
                            , Table.AddColumn(#"query C", "source query", each "query C")})
