testTable.addListener(SWT.PaintItem, new Listener() {

@Override
public void handleEvent(Event event) {
// Am I on collumn I need..?
if(event.index == 5) {
Image tmpImage = IMAGE_TEST_PASS;
int tmpWidth = 0;
int tmpHeight = 0;
int tmpX = 0;
int tmpY = 0;

tmpWidth = testTable.getColumn(event.index).getWidth();
tmpHeight = ((TableItem)event.item).getBounds().height;

tmpX = tmpImage.getBounds().width;
tmpX = (tmpWidth / 2 - tmpX / 2);
tmpY = tmpImage.getBounds().height;
tmpY = (tmpHeight / 2 - tmpY / 2);
if(tmpX <= 0) tmpX = event.x;
else tmpX += event.x;
if(tmpY <= 0) tmpY = event.y;
