示例 1
选取表 ({ [ key = "x", a = 1, b = null, c = 3 ], [ key = "y", a = 2, b = 4, c = null ] })
中的列“a”、“b”和“c”,并将它们逆透视为属性-值对。
使用情况
Table.Unpivot( Table.FromRecords({ [key = "x", a = 1, b = null, c = 3], [key = "y", a = 2, b = 4, c = null] }), { "a", "b", "c" }, "attribute", "value")
输出
Table.FromRecords({ [key = "x", attribute = "a", value = 1], [key = "x", attribute = "c", value = 3], [key = "y", attribute = "a", value = 2], [key = "y", attribute = "b", value = 4] })
