Table.LastN
Table.LastN(table as table, countOrCondition as any) as table
根据 countOrCondition
的值,返回 table
表的最后一行(或几行):
- 如果
countOrCondition
是数字,则将返回从末尾 -countOrCondition
位置开始的多行。 - 如果
countOrCondition
是条件,则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。
查找表的最后两行。

Table.LastN(
Table.FromRecords({

[CustomerID = 3, Name = "Paul", Phone = "543-7890"]

Table.FromRecords({
[CustomerID = 2, Name = "Jim", Phone = "987-6543"],
[CustomerID = 3, Name = "Paul", Phone = "543-7890"]
})
查找表中 [a] > 0 的最后几行。
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]
