I will atach a screen shot to demonstrate
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/NameConventionConfigurationBlock.java
public NameConventionConfigurationBlock(IStatusChangeListener context, IJavaProject project) {
		super(context, project);
		
		NameConventionAdapter adapter=  new NameConventionAdapter();
		String[] buttons= new String[] {
			 PreferencesMessages.getString("NameConventionConfigurationBlock.list.edit.button") 
		};
		fNameConventionList= new ListDialogField(adapter, buttons, new NameConventionLabelProvider());
		fNameConventionList.setDialogFieldListener(adapter);
		fNameConventionList.setLabelText(PreferencesMessages.getString("NameConventionConfigurationBlock.list.label")); 
		
		String[] columnsHeaders= new String[] {
			PreferencesMessages.getString("NameConventionConfigurationBlock.list.name.column"), 
			PreferencesMessages.getString("NameConventionConfigurationBlock.list.prefix.column"), 
			PreferencesMessages.getString("NameConventionConfigurationBlock.list.suffix.column"),			 
		};
		ColumnLayoutData[] data= new ColumnLayoutData[] {
			new ColumnWeightData(3),
			new ColumnWeightData(2),
			new ColumnWeightData(2)
		};
		
		fNameConventionList.setTableColumns(new ListDialogField.ColumnsDescription(data, columnsHeaders, true));
		unpackEntries();
		if (fNameConventionList.getSize() > 0) {
			fNameConventionList.selectFirstElement();
		} else {
			fNameConventionList.enableButton(0, false);
		}
