Table.RemoveLastN

Table.RemoveLastN( table as table, optional countOrCondition as any) as table

返回一个表，该表不包含表 table 的最后 countOrCondition 行。 删除的行数依赖于可选参数 countOrCondition。

• 如果忽略 countOrCondition，则只删除最后一行。
• 如果 countOrCondition 为数字，则将删除该数字那么多的行(从底部开始)。
• 如果 countOrCondition 是条件，将删除满足此条件的行，直到行不满足条件为止。

示例:

删除表的最后一行。

使用情况:

Table.RemoveLastN(Table.FromRecords({[CustomerID = 1, Name = "Bob", Phone = "123-4567"],[CustomerID = 2, Name = "Jim", Phone = "987-6543"],[CustomerID = 3, Name = "Paul", Phone = "543-7890"],[CustomerID = 4, Name = "Ringo", Phone = "232-1550"]}), 1)

输出:

Table.FromRecords({[CustomerID=1,Name="Bob",Phone="123-4567"],[CustomerID=2,Name="Jim",Phone="987-6543"],[CustomerID=3,Name="Paul",Phone="543-7890"]})

示例:

删除表中 [CustomerID] > 2 的最后几行。

使用情况:

Table.RemoveLastN(Table.FromRecords({[CustomerID = 1, Name = "Bob", Phone = "123-4567"],[CustomerID = 2, Name = "Jim", Phone = "987-6543"],[CustomerID = 3, Name = "Paul", Phone = "543-7890"],[CustomerID = 4, Name = "Ringo", Phone = "232-1550"]}), each [CustomerID] >= 2)

输出:

Table.FromRecords({[CustomerID=1,Name="Bob",Phone="123-4567"]})
