Adds one or several rows to DataFrame

df.append(
    "Mike", 15,
    "John", 17, 
    "Bill", 30,
)

If the compiler plugin is enabled, a typesafe overload of append is available for @DataSchema classes.

@DataSchema
data class Person(val name: String, val age: Int)

val df = dataFrameOf(
    Person("Mike", 15),
    Person("John", 17),
)

df.append(Person("Bill", 30))
