How to define input and result as DataTable in specs2?

Question

I was trying to use DataTables in specs2 to define both input and how the result should look like and could not get it to work. I was thinking something similar to the below code:

class MySpec extends Specification with DataTables {

"A Container" should {
"after data is added container should have the following data" in new TestContainer {
  "a"  | "flag" | "d"   |
  100  ! 1      ! "abc" |
  300  ! 1      ! "abc" |
  200  ! 0      ! "xyz" |>
  { (a, flag, d) =>
    container.add(Data(a, flag, d)) must not(throwA[Exception])
  } and
  "a"  | "flag" | "d"   |
  300  ! 1      ! "abc" |
  100  ! 1      ! "abc" |>
  { (a, flag, d) => ????
  }
}
}

Disclaimer: I am new to scala and specs. Some of the code was omitted for brevity.

After gaining better understanding of specs2 here is a solution I came up with:

class MySpec extends Specification with DataTables {

"A Container" should {
"after data is added container should have the following data" in new TestContainer {
  "a"  | "flag" | "d"   |
  100  ! 1      ! "abc" |
  300  ! 1      ! "abc" |
  200  ! 0      ! "xyz" |>
  { (a, flag, d) =>
    container.add(Data(a, flag, d)) must not(throwAn[Exception])
  }
  val state = container.list
  "a"  | "flag" | "d"   |
  300  ! 1      ! "abc" |
  100  ! 1      ! "abc" |>
  { (a, flag, d) => state must contain((a, flag, d))
  }
}
}

If order is important then second table can add tuples to some list and then compare 2 lists after second table is processed. Please, note this behavior is broken in 2.3, but works in 2.4-SNAPSHOT.
