如何固定jface中的Table组件的checkbox?

Question

org.eclipse.swt.widgets.Table组件中嵌入checkbox怎么固定阿，现在的问题是用鼠标滚动没问题，但是用上下左右键时，checkbox会跟着滚动条走，有点类似form中的checkbox,但这个是jface中的组件，那位大虾指点一下

Answer 1

更正下org.eclipse.swt.widgets.Table不是jface中的组件，没用到jface中的组件，不好意思哈

上面的代码有2个问题：
1.前三列都是checkbox，但是有2列老是重合到一块了，不知道为什么？
2.用上下左右键移动表里的数据时三列checkbox会跟着浮动，但是用鼠标拉滚动条确没有问题望大虾们指点下
