title: SWT: Changing the color of all the cells under a column
body: <p><img src="https://i.stack.imgur.com/4Tk8Y.jpg" alt="enter image description here"></p>
  
  <p>I've search around the web but have seen no answer. How can you change the color of all the cells under a column much like the first column in the picture? Which as you can see is a darker shade from the second and third column. Now I don't believe changing the TableItem's background will solve this, as it will only change that cell's color, the effect can be seen in the first row.</p>
  
  <p>Any Ideas?</p>
