title: Controls (Combo, Radio, Text) in column header SWT
body: <p>I've been searching everywhere, but I can't find a solution, nor an answer.</p>
  
  <p><strong>Can custom controls/widgets be placed in a column header of a table in SWT?</strong></p>
  
  <p>I can put those controls in the first row, but that is not the solution, because of the scrolling.</p>
  
  <p>The reason for the need is because I'm importing a CSV file, but sometimes the columns in it aren't in the same order as before, so I want to give the user an option to set which column is for what (Radio Buttons or Combo).</p>
  
  <p>Thank you.</p>
