其中YourFunctionNameHere 应替换为你的自定义函数名称(在本例中为 FilterColumns),并确保 "Column1", "Column2", "Column3" 包含了你想要保留的列名。 点击“完成”以保存更改。结论通过上述步骤,你已经成功地在 Power Query 中创建了一个自定义函数来筛选所需的列,并将其应用到你的数据中。这种方法不仅提高...

In that scenario, we could create the list inside the List.Contains function; this avoids changing the FilterList table query. = Table.SelectRows(#"Changed Type",eachList.Contains(FilterList[Filter List], [Item])) FilterList:the name of the query [Filter List]:the name of the column to ...
Volume (data sizes), velocity (rate of change), and variety (breadth of data sources and data shapes)Power Query offers the ability to work against a subset of the entire data set to define the required data transformations, allowing you to easily filter down and transform your data to a ...

这里通过PowerQuery逆透视功能先把它转换成一维表: 然后只需要写两个简单的度量值就可以实现第一个有数据的年度和该年度的数据: 第一个非空年度 = MIN('数据表'[年度])第一个非空数据 =CALCULATE( SUM('数据表'[数据]), FILTER(ALL('数据表'[年度]),'数据表'[年度]=MIN('数据表'[年度]))) 用DAX...
