EclipseRCP开发之如何让左右两边两个表格协同滚动

        有这样一个需求,左右各一个表格,要求拖动其中任意一个表格中的滚动条,另外一个都随之滚动,看起来就像是在一个表格中。具体如下图:


具体实现如下:
        /**
         * 设置左边(右边)表格的滚动条根据右边(左边)滚动条滚动而滚动
         
*/

        
// Make selection the same in both tables
        tParameterAlarm1.addListener(SWT.Selection, new Listener() {
            
public void handleEvent(Event event) {
                tParameterAlarm2.setSelection(tParameterAlarm1.getSelectionIndices());
            }

        }
);
        
// On Windows, the selection is gray if the table does not have focus.
        
// To make both tables appear in focus, draw teh selection background
        
// here.
        
// This part only works on version 3.2 or later.
        Listener eraseListener = new Listener() {
            
public void handleEvent(Event event) {
                
if ((event.detail & SWT.SELECTED) != 0{
                    GC gc 
= event.gc;
                    Rectangle rect 
= event.getBounds();
                    gc.setForeground(container.getDisplay().getSystemColor(
                                                          SWT.COLOR_LIST_SELECTION_TEXT));
                    gc.setBackground(container.getDisplay().getSystemColor(
                                                          SWT.COLOR_LIST_SELECTION));
                    gc.fillRectangle(rect);
                    event.detail 
&= ~SWT.SELECTED;
                }

            }

        }
;

        tParameterAlarm1.addListener(SWT.EraseItem, eraseListener);
        
// Make vertical scrollbars scroll together
        ScrollBar vBarLeft = tParameterAlarm1.getVerticalBar();
        vBarLeft.addListener(SWT.Selection, 
new Listener() {
            
public void handleEvent(Event event) {
                tParameterAlarm2.setTopIndex(tParameterAlarm1.getTopIndex());
            }

        }
);
        tParameterAlarm2.addListener(SWT.Selection, 
new Listener() {
            
public void handleEvent(Event event) {
                tParameterAlarm1.setSelection(tParameterAlarm2.getSelectionIndices());
            }

        }
);
        tParameterAlarm2.addListener(SWT.EraseItem, eraseListener);
        ScrollBar vBarRight 
= tParameterAlarm2.getVerticalBar();
        vBarRight.addListener(SWT.Selection, 
new Listener() {
            
public void handleEvent(Event event) {
                tParameterAlarm1.setTopIndex(tParameterAlarm2.getTopIndex());
            }

        }
);
其中tParameterAlarm1为左边表格的TableViewer,tParameterAlarm2为右边表格的TableViewer
