Table.LastN

Table.LastN(table as table, countOrCondition as any) as table

返回表 table 中的最后几行，具体取决于 countOrCondition 的值:

• 如果 countOrCondition 为数字，则将返回从位置(结尾 - countOrCondition)开始的多行。
• 如果 countOrCondition 是条件，将以升序位置返回满足此条件的行，直到行不满足条件为止。

示例:

查找表的最后两行。

使用情况:

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

输出:

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

示例:

查找表中 [a] > 0 的后几行。

使用情况:

Table.LastN(Table.FromRecords({[a = -1, b = -2], [a = 3, b = 4], [a = 5, b = 6]}), each _ [a] > 0)

输出:

Table.FromRecords({[a = 3, b = 4], [a = 5, b = 6]})
