Ok, it's the first time I try to use this control, and I can't figure this out.

Problems:
1. How to get 0 padding/inner margin in the cells? I want just the border as a colored line at the next close pixel to the control in the cell. Or if border set to none, I want the controls with no gap.
2. How do I actually add/remove rows& columns? I thought this was by setting the .ColumnCount property, but if I set it to 3, and then try to access the third column, it gives exception, so it's obviously just two columns, although it also looks like 3 on the form. ? I created it in designer with 2 columns though. But I don't understand how this hangs together..

plz.. ?

        z0.Dock = DockStyle.Fill
        z1.Dock = DockStyle.Fill
        z2.Dock = DockStyle.Fill
        z0.Padding = New Padding(0)
        z1.Padding = New Padding(0)
        z2.Padding = New Padding(0)


        tlpTest.CellBorderStyle = TableLayoutPanelCellBorderStyle.Single
        tlpTest.AutoSize = True
        tlpTest.Padding = New Padding(0)
        tlpTest.Margin = New Padding(0)


        tlpTest.ColumnCount = 1
        tlpTest.Controls.Add(z0, 0, 0)
        tlpTest.ColumnCount = 2
        tlpTest.Controls.Add(z1, 1, 0)
        tlpTest.ColumnCount = 3
        tlpTest.Controls.Add(z2, 2, 0)


        tlpTest.ColumnStyles.Item(0).SizeType = SizeType.Percent
        tlpTest.ColumnStyles.Item(0).Width = 33
        tlpTest.ColumnStyles.Item(1).SizeType = SizeType.Percent
        tlpTest.ColumnStyles.Item(1).Width = 33
        'tlpTest.ColumnStyles.Item(2).SizeType = SizeType.Percent
        'tlpTest.ColumnStyles.Item(2).Width = 33
