title: Change row/column span programmatically (tablelayoutpanel)
body: <p>I have a tablelayoutpanel. 2x2 - 2 columns 2 rows.</p>
  
  <p>For example, I added a button <em>button1</em> in a 1 row, second column. <em>button1</em> has a dock property set to Fill. VS Designer allows to set column/row span properties of <em>button1</em>.</p>
  
  <p>I want an availability to change row span property of <em>button1</em> <strong>programatically</strong>, so it can fill all second column(1 row and second row) and availability to set it back.</p>
  
  <p>How?</p>
