    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"]
    }),
    "Index"
)

Table.FromRecords({
    [CustomerID = 1, Name = "Bob", Phone = "123-4567", Index = 0],
    [CustomerID = 2, Name = "Jim", Phone = "987-6543", Index = 1],
    [CustomerID = 3, Name = "Paul", Phone = "543-7890", Index = 2],
    [CustomerID = 4, Name = "Ringo", Phone = "232-1550", Index = 3]
})

Example #2

从值 10 开始、按 5 递增将名为 "index" 的索引列添加到表。

Table.AddIndexColumn(
    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"]
    }),
    "Index",
    10,
    5
)

Result:

Table.FromRecords({
    [CustomerID = 1, Name = "Bob", Phone = "123-4567", Index = 10],
    [CustomerID = 2, Name = "Jim", Phone = "987-6543", Index = 15],
    [CustomerID = 3, Name = "Paul", Phone = "543-7890", Index = 20],
