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

}),
"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

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],
