使用方法：在PQ中新建一个【空查询】，然后在【视图】打开【高级编辑器】，清除原来的内容，输入以下内容，设置你的起始日期和结束日期，点完成就ok了，优雅方便高效~希望对大家有帮助！
大家也可以在此基础上调整代码，以便获得自己想要的分析维度。
let
// 设置起始日期、结束日期
自定义日期区间 = {Number.From(#date(2018,1,1)) .. Number.From(#date(2018,12,31))},
转换为表= Table.FromList(自定义日期区间, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
生成日期列= Table.RenameColumns(转换为表,{{"Column1", "日期"}}),
日期类型 = Table.TransformColumnTypes(生成日期列,{{"日期", type date}}),
整数日期 = Table.AddColumn(日期类型, "IntDate", each Date.ToText([日期],"yyyyMMdd")),
整数类型1 = Table.TransformColumnTypes(整数日期,{{"IntDate", Int64.Type}}),
