Is there an easy way to create two columns in a popup text window?

TextBox textBox    = new TextBox();
	textBox.Font       = new Font("Calibri", 11);
	textBox.Dock       = DockStyle.Fill;
	textBox.Multiline  = true;
	textBox.WordWrap   = false;
	textBox.ScrollBars = ScrollBars.Vertical;

	Form form            = new Form();
	form.Text            = "Recipe";
	form.Size            = new Size(400, 600);
	form.FormBorderStyle = FormBorderStyle.Sizable;
	form.StartPosition   = FormStartPosition.CenterScreen;
	form.Controls.Add(textBox);

	Graphics g = form.CreateGraphics();

	float targetWidth = 230;

	foreach (PropertyInfo property in properties)
    {
		string text = String.Format("{0}:t", Description);

		while (g.MeasureString(text,textBox.Font).Width < targetWidth)
			text += "t";

		textBox.AppendText(text + value.ToString() + "n");
	}

	g.Dispose();
	form.ShowDialog();
