C# Align Labels

Hello guys. I have a simple 2D array with 9 elements, and i loop through them and I'm trying to write them on a form. But they aren't aligned properly. I tried with PadLeft but it didn't work. Here is my code:

        int[][] array = 
        {
            new int[3] {-1, 2, 3},
            new int[3] {4, 53, 6}, 
            new int[3] {7, 8, -9} 
        };

        public Form1()
        {
            InitializeComponent();
            Load += new EventHandler(Form1_Load);
        }

        void Form1_Load(object sender, EventArgs e)
        {
            string myString;
            int width = 10, height = 10;
            int maxLenght = array[0][0];

            Label[] labels = new Label[3];
            for (int i = 0; i < 3; ++i)
            {
                myString = string.Empty;
                for (int j = 0; j < 3; ++j)
                {
                    myString += array[i][j].ToString() + "  ";
                }
                labels[i] = new Label();
                labels[i].AutoSize = true;
                labels[i].Location = new Point(width, height += 20);
                labels[i].Text = myString.PadLeft(5);

                this.Controls.Add(labels[i]);
            }
        }

and here is my result: http://img23.imageshack.us/img23/2306/alignedy.png

I noticed if all elements has the same lenght, they are aligned correctly. 

Thanks!
