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[] CROPPRING_SEASONS = { "1", "2" ,"3", "4", "5" };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);this.viewer = viewer;editors = new CellEditor[10];editors[0] = new ComboBoxCellEditor(viewer.getTable(), CROPPRING_SEASONS, SWT.READ_ONLY);editors[1] = new TextCellEditor(viewer.getTable());editors[2] = new ComboBoxCellEditor(viewer.getTable(), GENERATION, SWT.READ_ONLY);editors[3] = new ComboBoxCellEditor(viewer.getTable(), GENERATION, SWT.READ_ONLY);editors[4] = new ComboBoxCellEditor(viewer.getTable(), ROUNDS_INTER, SWT.READ_ONLY);editors[5] = new ComboBoxCellEditor(viewer.getTable(), ROUNDS_SELFING, SWT.READ_ONLY);editors[6] = new TextCellEditor(viewer.getTable());editors[7] = new TextCellEditor(viewer.getTable());editors[8] = new TextCellEditor(viewer.getTable());editors[9] = new TextCellEditor(viewer.getTable());}@Overrideprotected CellEditor getCellEditor(Object element) {InputInfoItem item = (InputInfoItem) element;for(int i = 1 ; i<= 10 ; i++){if(item.getId().equals(String.valueOf(i)))return editors[i-1];}/*if (item.getId().equals("1")) {return editors[0];} else if (item.getId().equals("2")) {return editors[1];} */return null;}@Overrideprotected boolean canEdit(Object element) {return true;}@Overrideprotected Object getValue(Object element) {InputInfoItem item = (InputInfoItem) element;if (item.getId().equals("1")) {for(int i = 0 ; i<CROPPRING_SEASONS.length ; i++){if(CROPPRING_SEASONS[i].equals(item.getValue()))return new Integer(i);}        } else if (item.getId().equals("2")) {        return item.getValue();        } else if (item.getId().equals("3")) {        for(int i = 0 ; i<GENERATION.length ; i++){if(GENERATION[i].equals(item.getValue()))return new Integer(i);}        } else if (item.getId().equals("4")) {        for(int i = 0 ; i<GENERATION.length ; i++){if(GENERATION[i].equals(item.getValue()))return new Integer(i);}        } else if (item.getId().equals("5")) {        for(int i = 0 ; i<ROUNDS_INTER.length ; i++){if(ROUNDS_INTER[i].equals(item.getValue()))return new Integer(i);}        } else if (item.getId().equals("6")) {        for(int i = 0 ; i<ROUNDS_SELFING.length ; i++){if(ROUNDS_SELFING[i].equals(item.getValue()))return new Integer(i);}        } else if (item.getId().equals("7")) {        return item.getValue();        } else if (item.getId().equals("8")) {        return item.getValue();        } else if (item.getId().equals("9")) {        return item.getValue();        } else if (item.getId().equals("10")) {        return item.getValue();        }return null;}@Overrideprotected void setValue(Object element, Object value) {InputInfoItem item = (InputInfoItem) element;if(item.getId().equals("1")) {item.setValue(CROPPRING_SEASONS[Integer.parseInt(value.toString())]);} else if(item.getId().equals("2")) {item.setValue(value.toString());} else if(item.getId().equals("3")) {item.setValue(GENERATION[Integer.parseInt(value.toString())]);} else if(item.getId().equals("4")) {item.setValue(GENERATION[Integer.parseInt(value.toString())]);} else if(item.getId().equals("5")) {item.setValue(ROUNDS_INTER[Integer.parseInt(value.toString())]);} else if(item.getId().equals("6")) {item.setValue(ROUNDS_SELFING[Integer.parseInt(value.toString())]);} else if(item.getId().equals("7")) {item.setValue(value.toString());} else if(item.getId().equals("8")) {item.setValue(value.toString());} else if(item.getId().equals("9")) {item.setValue(value.toString());} else if(item.getId().equals("10")) {item.setValue(value.toString());}         this.viewer.refresh();}}

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);
