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);

}

@Override

for(int i = 1 ; i<= 10 ; i++){

}

}

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));

TableViewerColumn tableViewerColumn = new TableViewerColumn(tableViewer,tableColumn2);

tableViewerColumn.setEditingSupport(new MyEditingSupport(tableViewer));

//省略具体添加

tableViewer.setLabelProvider()

tableViewer.setContentProvider();

tableViewer.setInput(inputInfoList)
