How to insert a horizontal line inbetween the table layout panel

Thanks in advance....Say for example I have 5 Rows in a tablelayout panel.

But how do I add the line after every 2 rows?

So, the first thing we observe is there should not be any seperator/vertical gridlines between columns.
Then how do we add the line after 2 rows?
Also, usually we add lines/labels for each cell in a column. But in my case I need a full line and not for a cell.

What I have tried:

By using label control. Clear Text of label, set AutoSize to false , Borderstyle to FIxedSingle. and Height to 1.

FWIW, this is trivial with WPF / UWP: A "Grid"; and a Rectangle with Height = 1+ spanning one or more columns.

Try setting TableLayoutPanel.SetColumnSpan, see: TableLayoutPanel.SetColumnSpan(Control, Int32) Method (System.Windows.Forms) | Microsoft Docs[^]

You can use custom Painting method. See: c# - Draw only outer border for TableLayoutPanel Cells - Stack Overflow[^]. For example:

C#

private void tableLayoutPanel_CellPaint(object sender, TableLayoutCellPaintEventArgs e)
{
        if(e.Row > 1 && e.Row % 2 == 0 ) 
            e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Right, e.CellBounds.Top));
}

Or... you can create custom control, which will display data in 2 rows and horizontal line below.
