Table.RemoveLastN

返回一个表，其中删除了最后 N 行。

Syntax

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

Remarks

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。

Examples

Example #1

删除表的最后一行。

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
)

Result:

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

Example #2

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"]
