Populate a datagrid from a Loop - apache-flex

Question

I'm just starting to learn flex and AS3
I'm trying to get information into a datagrid that originates from a mathmatical formula. For example if I have 100 and I subtract 5 from it and continue to do so until it reaches 0 so my grid would be something like:
100 | -5
95 | -5
90 | -5
...
...
5 | -5
0
I'm guessing that it needs to do something like this but can't find any examples of how to impliment something like this:
var i:Number = 100;
do {
add row to datagrid
i-5;
} while (i < 0);
Thanks
Dave

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="onCreationComplete()">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
private var myDataProvider:ArrayCollection = new ArrayCollection();
private function onCreationComplete():void
{
var i:int = 100;
while(i >= 0) {
myDataProvider.addItem({"index" : i});
i -= 5;
}
}

</mx:Script>
<mx:DataGrid dataProvider="{ myDataProvider }" width="100%" height="100%">
<mx:columns>
<mx:DataGridColumn dataField="index" headerText="#"/>
</mx:columns>
</mx:DataGrid>
</mx:Application>
Also take a look in Flex language reference DataGrid, there is example at the bottom of the page.
