Power BI 转型

Question

我正在尝试转换我在 PowerBI 中的日历 table。

日历数据如下所示：

Name	Event	Detail	Start Date	End Date
Name 1	Event A	Detail A	12/2/2020	15/2/2020
Name 2	Event A	Detail A	12/2/2020	15/2/2020
Name 3	Event A	Detail A	12/2/2020	15/2/2020
Name 2	Event B	Detail B	22/2/2020	25/2/2020
Name 3	Event B	Detail B	22/2/2020	25/2/2020
Name 4	Event B	Detail B	22/2/2020	25/2/2020
Name 1	Event C	Detail C	23/2/2020	27/2/2020

我希望它看起来像这样：

Name	Event	Detail	Date
Name 1	Event A	Detail A	12/2/2020
Name 1	Event A	Detail A	13/2/2020
Name 1	Event A	Detail A	14/2/2020
Name 1	Event A	Detail A	15/2/2020
Name 2	Event A	Detail A	12/2/2020
Name 2	Event A	Detail A	13/2/2020
Name 2	Event A	Detail A	14/2/2020
Name 2	Event A	Detail A	15/2/2020
Name 3	Event A	Detail A	12/2/2020
Name 3	Event A	Detail A	13/2/2020
Name 3	Event A	Detail A	14/2/2020
Name 3	Event A	Detail A	15/2/2020
Name 2	Event B	Detail B	22/2/2020
Name 2	Event B	Detail B	23/2/2020
Name 2	Event B	Detail B	24/2/2020
Name 2	Event B	Detail B	25/2/2020
Name 3	Event B	Detail B	22/2/2020
Name 3	Event B	Detail B	23/2/2020
Name 3	Event B	Detail B	24/2/2020
Name 3	Event B	Detail B	25/2/2020
Name 4	Event B	Detail B	22/2/2020
Name 4	Event B	Detail B	23/2/2020
Name 4	Event B	Detail B	24/2/2020
Name 4	Event B	Detail B	25/2/2020
Name 1	Event C	Detail C	23/2/2020
Name 1	Event C	Detail C	24/2/2020
Name 1	Event C	Detail C	25/2/2020
Name 1	Event C	Detail C	26/2/2020
Name 1	Event C	Detail C	27/2/2020

如何在查询编辑器中执行此操作？

提前致谢！

根据需要修改任何名称。

let
  Source = Excel.CurrentWorkbook(){[Name = "Table1"]}[Content], 
  #"Changed Type" = Table.TransformColumnTypes(
    Source, 
    {
      {"Name", type text}, 
      {"Event", type text}, 
      {"Detail", type text}, 
      {"Start Date", type date}, 
      {"End Date", type date}
    }
  ), 
  #"Added Column: Number of Days" = Table.AddColumn(
    #"Changed Type", 
    "Total Days", 
    each 1 + Duration.Days([End Date] - [Start Date])
  ), 
  #"Added Column: List" = Table.AddColumn(
    #"Added Column: Number of Days", 
    "Days to Add", 
    each {1 .. [#"Total Days"]}
  ), 
  #"Expanded Days to Add" = Table.ExpandListColumn(#"Added Column: List", "Days to Add"), 
  #"Added Column: New Dates" = Table.AddColumn(
    #"Expanded Days to Add", 
    "Custom", 
    each Date.AddDays([Start Date], [Days to Add] - 1), 
    type date
  )
in
  #"Added Column: New Dates"
