eclipse rcp Table 不能上下滚动

 

 

如图，该表格中数据当前页面显示不下，需要鼠标向下滚动，但是目前无法向下滚动，也可以发现没有向下的滚动条。创建这部分区域代码如下：

	private void createSqlHisTable(Composite parent) {
		Composite composite = new Composite(parent,SWT.NONE);
		GridLayout gridLayout = new GridLayout(1, false);
		gridLayout.marginHeight = 0;
		gridLayout.marginWidth = 0;
		gridLayout.horizontalSpacing = 0;
		gridLayout.verticalSpacing = 0;
		composite.setLayout(gridLayout);
		composite.setLayoutData(new GridData(GridData.FILL_HORIZONTAL)); 
		
		this.searchText = new Text(composite, SWT.BORDER);
                this.searchText.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
        
        
		sqlHisTable = new Table(composite, SWT.MULTI | SWT.FULL_SELECTION | SWT.V_SCROLL | SWT.H_SCROLL);
		sqlHisTable.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));  // 重要
		sqlHisTable.setData(this);
		sqlHisTable.setHeaderVisible(true);
		
		sqlHisTable.setMenu(createPopUpMenu());
		
		sqlHisTable.addSelectionListener(widgetDefaultSelectedAdapter(e -> {
			TableItem[] items = sqlHisTable.getSelection();
			if (items.length > 0)
				editEntry(items[0]);
		}));
		sqlHisTable.addSelectionListener(widgetSelectedAdapter(e -> {
			chosenTarget = "sqlHisTable";
		}));
		
		for(int i = 0; i < columnNames.length; i++) {
			TableColumn column = new TableColumn(sqlHisTable, SWT.NONE);
			column.setText(columnNames[i]);
			column.setWidth(columnWidth[i]);
			final int columnIndex = i;
			column.addSelectionListener(widgetSelectedAdapter(e -> sort(columnIndex)));
		}
		
		
//		loadQMLogDataFromFile();
	    
	    UIUtils.addFocusTracker(this.getSite(), SQL_INSPECTION_CONTROL_ID, sqlHisTable);
	    sqlHisTable.addDisposeListener(e -> {
//	    	UIUtils.removeFocusTracker(SqlInspectionView.this.getSite(), sqlHisTable);
	    	QMUtils.unregisterMetaListener(this);
			UIUtils.dispose(sqlHisTable);
		});
	}

　　

设置table上下、左右滚动是在创建table时设置样式: 

SWT.V_SCROLL | SWT.H_SCROLL

那么在当前组件 GridData 页面布局下，我对table设置了

sqlHisTable.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

这种水平填充，那么table可以左右滚动，如果需要设置table上下滚动 则需要设置
sqlHisTable.setLayoutData(new GridData(GridData.FILL_VERTICAL));

那么这里需要表格上下左右滚动，直接设置为

sqlHisTable.setLayoutData(new GridData(GridData.FILL_BOTH));
