I don't know anything about scala swing, but that doesn't work because
like it says, you're passing an Array[Array[String]] and it wants an
Array[Array[Any]]. Arrays aren't covariant.

Create them like Array[Any]("foo", "bar", ...) and at least it will
compile.

Also, if the Table constructor is rewritten something more like this:

def this(_rowData: Array[_ <: Array[_]], _columnNames: Seq[_]) = {
this()
val rowData = _rowData.asInstanceOf[Array[Array[Any]]]
val columnNames = _columnNames.asInstanceOf[Seq[Any]]

it should allow you to call it the way you're calling it without
altering anything else. I don't want to modify it because in my swingy
ignorance I could easily be overlooking something, but if I'm not maybe
that will turn up down the road.

Ok, I got it to compile and the data shows, but there are no headers?

import scala.swing._

object Gui {
 def main(args: Array[String]) {
   var initial = Array(
     Array("John", "Doe", "26"),
     Array("Jim", "Smith", "55"),
     Array("Robert", "Lang", "43"))

   val names = Array("First name", "Last name", "Age")

   var memTable = new Table(initial.asInstanceOf[Array[Array[Any]]], names.asInstanceOf[Array[Any]])

   val main = new MainFrame {
     contents = memTable
   }
   main.visible = true
 }
}

The headers only show up if you put it in a scrollpanel... this is actually a swing behavior... don't ask me why the heck swing does this, though. See the JTable docs for more info:

Note that if you wish to use a JTable in a standalone view (outside of a JScrollPane) and want the header displayed, you can get it using getTableHeader() and display it separately.
