[//]: # (title: append)
Adds one or several rows to [`DataFrame`](DataFrame.md)
```kotlin
df.append(
"Mike", 15,
"John", 17,
"Bill", 30,
)
```
If the [compiler plugin](Compiler-Plugin.md) is enabled, a typesafe overload of `append` is available for `@DataSchema` classes.
```kotlin
@DataSchema
data class Person(val name: String, val age: Int)
```
```kotlin
val df = dataFrameOf(
Person("Mike", 15),
Person("John", 17),
)
df.append(Person("Bill", 30))
```
