C# :: Draw Border Around TableLayoutPanel Cell

I would like to draw a border arround a cell in a TableLayoutPanel but without also making a connection between the columns. I just want an outer border.

private void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e) {
if (e.Row == 0) {
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Right, e.CellBounds.Top));
e.Graphics.DrawLine(Pens.Black, new Point(e.CellBounds.Left, e.CellBounds.Bottom), new Point(e.CellBounds.Right, e.CellBounds.Bottom));
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
}
}

This line

e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));

also paints connections, where i don't want them. How can i just make a outerb order arround a cell and is there a easier way to do it? Here's also an image of what i want. I don't know if i described it right.
