Table.AddRankColumn(table as table, newColumnName as text, comparisonCriteria as any, optional options as nullable record) as table

关于

将名为 newColumnName 的列追加到 table，并使用由 comparisonCriteria 描述的一个或多个其他列进行排名。高级用户可以使用 options 中的 RankKind 选项来选择更具针对性的排名方法。

示例 1

向表中添加名为“RevenueRank”的列，以便对“Revenue”列进行从高到低的排名。

使用情况

Table.AddRankColumn(
    Table.FromRecords({
        [CustomerID = 1, Name = "Bob", Revenue = 200],
        [CustomerID = 2, Name = "Jim", Revenue = 100],
        [CustomerID = 3, Name = "Paul", Revenue = 200],
        [CustomerID = 4, Name = "Ringo", Revenue = 50]
    }),
    "RevenueRank",
    {"Revenue", Order.Descending},
    [RankKind = RankKind.Competition]
)

输出

Table.FromRecords({
    [CustomerID = 1, Name = "Bob", Revenue = 200, RevenueRank = 1],
    [CustomerID = 3, Name = "Paul", Revenue = 200, RevenueRank = 1],
    [CustomerID = 2, Name = "Jim", Revenue = 100, RevenueRank = 3],
    [CustomerID = 4, Name = "Ringo", Revenue = 50, RevenueRank = 4]
