Examples​

Example #1​

Pievienot skaitļu kolonnu ar nosaukumu "TotalPrice" tabulā, ar katru vērtību kā kolonnu [Price] un [Shipping] summu.

Table.AddColumn(
    Table.FromRecords({
        [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100.0, Shipping = 10.00],
        [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5.0, Shipping = 15.00],
        [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25.0, Shipping = 10.00]
    }),
    "TotalPrice",
    each [Price] + [Shipping],
    type number
)

Result:

Table.FromRecords({
    [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100, Shipping = 10, TotalPrice = 110],
    [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5, Shipping = 15, TotalPrice = 20],
    [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25, Shipping = 10, TotalPrice = 35]
})
