一、要实现这个功能必须提供一个实现ICellModifier的类。内容如下
import org.eclipse.jface.viewers.ICellModifier;
import org.eclipse.jface.viewers.TableViewer;
import org.eclipse.swt.widgets.TableItem; public class MyCellModifier implements ICellModifier{
        private TableViewer tv;
        public static String[] NAMES ={"张三","李四","小红","翠花"};
       
        public MyCellModifier(TableViewer tv){
                this.tv = tv;
        }
        public boolean canModify(Object element, String property) {
            return true;
        }         public Object getValue(Object element, String property) {
            People p = (People)element;
            if(property.equals("name")){
                return new Integer(getNameIndex(p.getName()));
            }else if(property.equals("sex")){
                return new Boolean(p.getSex().equals("男"));
            }else if(property.equals("age")){
                return String.valueOf(p.getAge());
            }
            throw new RuntimeException("error column name : " + property);
        }
        private int getNameIndex(String name){
            for(int i=0;i                 if(NAMES[i].equals(name)){
                    return i;
                }
            }
            return -1;
        }         public void modify(Object element, String property, Object value) {
            TableItem item = (TableItem)element;
            People p = (People)item.getData();
            if (property.equals("name")){
                Integer comboIndex = (Integer)value;
                if(comboIndex.intValue() == -1){
                    return ;
                }
                String newName = NAMES[comboIndex.intValue()];
                p.setName(newName);
            }else if(property.equals("sex")){
                Boolean newValue = (Boolean)value;
                System.out.println(newValue);
                if(newValue.booleanValue()){
                    p.setSex("男");
                }else{
                    p.setSex("女");
                }
            }else if (property.equals("age")){
                String newValue = (String)value;
                if(newValue.equals("")){
                    return ;
                }
                Integer newAge = new Integer(newValue);
                p.setAge(newAge);
            }else{
                throw new RuntimeException("错误列名:" + property);
            }
            tv.update(p, null);
        }
       
    }
二、好了，有了这个类，下一部就是如何把它和TestTableViewer关联起来，在TestTableViewer中setInput()后加入如下内容
tableViewer.setColumnProperties(new String[]{"id","name","sex","age","createDate"});
        CellEditor[] cellEditor = new CellEditor[5];
        cellEditor[0] = null;
        cellEditor[1] = new ComboBoxCellEditor(tableViewer.getTable(),MyCellModifier.NAMES,SWT.READ_ONLY);
        cellEditor[2] = new CheckboxCellEditor(tableViewer.getTable());
        cellEditor[3] = new TextCellEditor(tableViewer.getTable());
        cellEditor[4] = null;
        tableViewer.setCellEditors(cellEditor);
        ICellModifier modifier = new MyCellModifier(tableViewer);
        tableViewer.setCellModifier(modifier);我们让名字这一列用下拉条来编辑，让性别这一列变成类似checkbox的操作，让年龄这一类变成直接输入
ok，尝试一下。
三、问题出现，如果年龄的地方我们输入一个非数字呢，所以为了安全起见，我们加入一个验证器，禁止用户输入非数字
在上边的内容下加入
Text text = (Text)cellEditor[3].getControl();
        text.addVerifyListener(new VerifyListener(){
            public void verifyText(VerifyEvent e){
                String inStr = e.text;
                if (inStr.length() > 0){
                    try{
                        Integer.parseInt(inStr);
                        e.doit = true;
                    }catch(Exception ep){
                        e.doit = false;
                    }
                }
            }
        });好了，再试试是否不能输入非整数了？解决。其实还是有些问题的，试着输入个0，呵呵。这里就需要你自己按照自己的实际需求来实现了。
但作为demo这个的目的已经达到了。
