使用情况

Table.FromPartitions(    "Year",    {         {             1994,            Table.FromPartitions(                "Month",                {                     {                         "Jan",                        Table.FromPartitions(                            "Day",                            {                                 { 1, #table({ "Foo" }, { { "Bar" } }) },                                { 2, #table({ "Foo" }, { { "Bar" } }) }                             }                        )                     },                    {                         "Feb",                        Table.FromPartitions(                            "Day",                            {                                 { 3, #table({ "Foo" }, { { "Bar" } }) },                                { 4, #table({ "Foo" }, { { "Bar" } }) }                             }                        )                     }                 }            )         }     })

输出

Table.FromRecords({     [        Foo = "Bar",        Day = 1,        Month = "Jan",        Year = 1994    ],    [        Foo = "Bar",        Day = 2,        Month = "Jan",        Year = 1994    ],    [        Foo = "Bar",        Day = 3,        Month = "Feb",        Year = 1994    ],    [        Foo = "Bar",        Day = 4,        Month = "Feb",        Year = 1994    ] })
