title: Draw borders around some cells in a tablelayoutpanel
body: <p>Don't ask why but I have the requirement to draw a border around certain cells in a <code>TableLayoutPanel</code>. </p>
  
  <p>For example, for simplicity, lets say I have a 1 row, 5 column <code>TableLayoutPanel</code>. Each cell has a button in it. I would like to draw a box around the first 3 cells and then another box around the last 2 cells. So two boxes total.</p>
  
  <p>Any suggestions on how to accomplish that?</p>
  
  <p>Thanks.</p>
