### Example

````scala

import slick.jdbc.H2Profile.api._

import slick.migration.api._

val db = Database.forConfig("example-config")

implicit val dialect: H2Dialect = new H2Dialect

class MyTable(tag: Tag) extends Table[(Int, String)](tag, "my_table") {

  val col1 = column[Int]("col1")

  val col2 = column[String]("col2")

  val index1 = index("idx1", col1)

  def * = (col1, col2)

}

val MyTable = TableQuery[MyTable]

val init =

  TableMigration(MyTable)

    .create

    .addColumns(_.col1, _.col2)

    .addIndexes(_.index1)

    .renameColumn(_.col1, "col3")

val seed =

  SqlMigration("insert into myTable (col1, col2) values (10, 20)")

  

val migration = init & seed

db.run(migration())
