Table.MaxN

Syntax

Table.MaxN(table as table, comparisonCriteria as any, countOrCondition as any) as table

About

Returns the largest row(s) in the table, given the comparisonCriteria. After the rows are sorted, the countOrCondition parameter must be specified to further filter the result. Note the sorting algorithm cannot guarantee a fixed sorted result. The countOrCondition parameter can take multiple forms:

• If a number is specified, a list of up to countOrCondition items in ascending order is returned.
• If a condition is specified, a list of items that initially meet the condition is returned. Once an item fails the condition, no further items are considered.

Example 1

Find the row with the largest value in column [a] with the condition [a] > 0, in the table. The rows are sorted before the filter is applied.

Usage

Table.MaxN(
    Table.FromRecords({
        [a = 2, b = 4],
        [a = 0, b = 0],
        [a = 6, b = 2]
    }),
    "a",
    each [a] > 0
)

Output

Table.FromRecords({
    [a = 6, b = 2],
    [a = 2, b = 4]
})

Example 2

Find the row with the largest value in column [a] with the condition [b] > 0, in the table. The rows are sorted before the filter is applied.

Usage

Table.MaxN(
    Table.FromRecords({
        [a = 2, b = 4],
        [a = 8, b = 0],
        [a = 6, b = 2]
    }),
    "a",
    each [b] > 0
)

Output

Table.FromRecords({})
