Table.RemoveLastN

语法

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

关于

返回一个表，该表不包含表 table 中最后的 countOrCondition 行。 删除的行数取决于可选参数 countOrCondition。

• 如果省略 countOrCondition，则只删除最后一行。
• 如果 countOrCondition 是数字，则将删除多个行（从底部开始）。
• 如果 countOrCondition 是条件，则将删除满足条件的行，直到出现不满足条件的行为止。

示例 1

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"]
    }),

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

        [CustomerID = 2, Name = "Jim", Phone = "987-6543"],
        [CustomerID = 3, Name = "Paul", Phone = "543-7890"],
