Table.ToList Function in Power Query

The Table.ToList converts a table into a list by applying the specified combining function to each row of values in a table.

let
  MyTable = Table.FromRecords(
    {
      [CustomerID = 1, Name = "Ashish", Phone = "123-4567"], 
      [CustomerID = 2, Name = "Katrina", Phone = "987-6543"],

      [CustomerID = 8, Name = "Anjali", Phone = "574-8864"]
