Table.RemoveLastN

Syntax

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

About

Returns a table that does not contain the last countOrCondition rows of the table table. The number of rows removed depends on the optional parameter countOrCondition.

• If countOrCondition is omitted only the last row is removed.
• If countOrCondition is a number, that many rows (starting at the bottom) will be removed.
• If countOrCondition is a condition, the rows that meet the condition will be removed until a row does not meet the condition.

Example 1

Remove the last row of the table.

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

        [CustomerID = 3, Name = "Paul", Phone = "543-7890"],
        [CustomerID = 4, Name = "Ringo", Phone = "232-1550"]
