swt/jface使用EditingSupport 为同一列提供不同类型的编辑器CellEditor

自定义MyEditingSupport实现EditingSupport，代码如下

import org.eclipse.jface.viewers.CellEditor;
import org.eclipse.jface.viewers.ComboBoxCellEditor;
import org.eclipse.jface.viewers.EditingSupport;
import org.eclipse.jface.viewers.StructuredViewer;
import org.eclipse.jface.viewers.TableViewer;
import org.eclipse.jface.viewers.TextCellEditor;
import org.eclipse.swt.SWT;

public class MyEditingSupport extends EditingSupport {

	private static final String[] GENERATION = { "F1DH", "F2" ,"F3", "F4", "F5" ,"F6", "F7" ,"F8"};
	private static final String[] ROUNDS_INTER = { "1", "2" ,"3", "4:3" };
	private static final String[] ROUNDS_SELFING = { "1", "2" ,"3", "4", "5" ,"6" ,"7" ,"8:5" };
	private CellEditor[] editors;
	private StructuredViewer viewer;

	public MyEditingSupport(TableViewer viewer) {
		super(viewer);

	}

	@Override

        } else if (item.getId().equals("2")) {

}

表格共有三列、十行，为第三列添加EditingSupport

tableViewer = new TableViewer(this,SWT.FULL_SELECTION);
		table = tableViewer.getTable();
		table.setHeaderVisible(true);
		table.setLinesVisible(true);
		TableColumn tableColumn = new TableColumn(table, SWT.NONE);
		tableColumn.setWidth(60);
		tableColumn.setText("ID");
		TableColumn tableColumn1 = new TableColumn(table, SWT.NONE);
		tableColumn1.setWidth(220);
		tableColumn1.setText("Name");
		TableColumn tableColumn2 = new TableColumn(table, SWT.NONE);
		tableColumn2.setWidth(80);
		tableColumn2.setText("Value");
		this.setLayout(new FillLayout());
		this.setBackground(new Color(Display.getCurrent(), 255, 255, 255));


		[color=red]TableViewerColumn tableViewerColumn = new TableViewerColumn(tableViewer,tableColumn2);
	    tableViewerColumn.setEditingSupport(new MyEditingSupport(tableViewer));[/color]		
	    tableViewer.setLabelProvider();
	    tableViewer.setContentProvider();

	    tableViewer.setInput(inputInfoList);
