UI - How to make Columns in a Drop Down List Selection?

Question

I am altering a code from Peter Kahrel "Beginning Script UI". I am trying to make a searchable drop down list that will have 4 columns. So far, the search works and I have headings in the search, but I cannot seem to make the columns for the actual data. I believe I need to change the type_ahead since the array is looking at this data. I'm stuck in the water. Can someone tell me what I need to do to get the list to show up as columns? How do I turn the picked = type_ahead data into four columns? Code and Screenshot below:
picked = type_ahead (["bat", "bear", "beaver", "bee", "cat", "cats_and_dogs",
"dog", "maggot", "moose", "moth", "mouse"]);
function type_ahead (array)
var w = new Window ("dialog", "Quick select");
var entry = w.add ("edittext", [0, 0, 800, 22]);
entry.active = true;
var list = w.add ("listbox",  [0, 0,800, 500], "",
{numberOfColumns: 4, showHeaders: true,
columnTitles: ["Non-Approved Word", "Approved Alternative", "Approved Use", "Non-Approved Use"], columnWidths: [200,200,200,200]});
list.selection = 0;
entry.onChanging = function ()
var temp = this.text;
list.removeAll ();
for (var i = 0; i < array.length; i++)
if (array[i].toLowerCase().indexOf (temp) == 0)
list.add ("item", array[i]);
if (list.items.length > 0)
list.selection = 0;
entry.onChange = function () {w.close (1)}
if (w.show () != 2)
return list.selection.text;
else
w.close ();

Hi Peter,
This is one of those developments that push the limits of my knowledge-base and when things do that, I lose sleep until I figure it out. With that said :-) here is where I have ended up.
Basically I made a new array for the table data.  I then use an array lookup to sort the array in the listbox based on the 0 array item. See the code below. Once it is loaded type in "b" and the list will start to sort.
I need to try to get this to work as a pallete instead of a dialog box. Do palletes support this type of functionality?
var newarray = new Array(
new Array('Butterfly ','has wings','can fly'),
new Array('bohemith moth','has wings','cannot fly very good'),
new Array('word 3','replacement word','use case'));
picked = type_ahead (newarray);
function type_ahead (array)
var w = new Window ("dialog", "STE Checker");
var entry = w.add ("edittext", [0, 0, 800, 22]);
entry.active = true;
var list = w.add ("listbox",  [0, 0,800, 500], "",
{numberOfColumns: 3, showHeaders: true,
columnTitles: ["Column 1",  "Column 2", "Column 3" ], columnWidths: [200,200,400]});
list.selection = 0;
entry.onChanging = function ()
var temp = this.text;
list.removeAll ();
for (var i = 0; i < array.length; i++)
if (array[i][0].toLowerCase().indexOf (temp) == 0)
with (list.add ("item", array[i][0]))
subItems[0].text = array[i][1];
subItems[1].text = array[i][2];
if (list.items.length > 0)
list.selection = 0;
entry.onChange = function () {}
if (w.show () != 2)
return list.selection.text;
else
w.close ();
