Что-то типа:

textBlock.text="text1, text2,text2,text2, text3 \ntext4,text2,text2, text5, text6";
 
var tableRows:Array = textBlock.text.split("\n"); 
var cellText:Array = new Array();
var i:int, j:int;
 
for (i = 0; i < tableRows.length; i++)
{
	cellText[i] = (tableRows[i] as String).split(",");	
}
 
for (i=0; i<cellText.length; i++){
	var rows:Array = cellText[i] as Array;
 
	for (j=0; j<rows.length; j++)
	{
		var cell:Text = new Text;
		cell.text = rows[j] as String;
		cell.move(i*(this.width-8)/colsNum+5, j*(this.height-8)/rowsNum+5);
		this.addChild(cell);
	}
}
