我正在学习摇摆，并且对于将行插入表格有一个疑问。 我的要求是我必须通过按添加按钮添加新行。但我无法继续。请找到以下代码：
如果有人知道请帮助我......
{public class TableShellExample {
Display d;
Shell s;
TableViewer tableViewer;
CellEditor cellEditor;
TableShellExample(){
d = new Display();
s = new Shell();
s.setSize(250,250);
s.setText("Table Shell Example");
GridLayout g1 = new GridLayout();
g1.numColumns = 3;
s.setLayout(g1);
final Table table = new Table(s,SWT.BORDER |SWT.CHECK|SWT.MULTI | SWT.FULL_SELECTION);
GridData gd = new GridData(GridData.FILL_BOTH);
gd.horizontalSpan = 3;
table.setLayoutData(gd);
table.setHeaderVisible(true);
TableColumn tc1 = new TableColumn(table, SWT.LEFT);
TableColumn tc2 = new TableColumn(table,SWT.CENTER);
TableColumn tc3 = new TableColumn(table,SWT.CENTER);
tc1.setText("FIRST NAME");
tc2.setText("LAST NAME");
tc3.setText("ADDRESS");
tc1.setWidth(70);
tc2.setWidth(70);
tc3.setWidth(80);
TableItem it1 = new TableItem(table,SWT.NONE);
it1.setText(new String[]{"aaa","bbb","pune"});
TableItem it2 = new TableItem(table,SWT.NONE);
it2.setText(new String[]{"aaa","bbb","pune"});
TableItem it3 = new TableItem(table,SWT.NONE);
it3.setText(new String[]{"aaa","bbb","pune"});
//tableViewer = new TableViewer(table);
//tableViewer.setColumnProperties(tc1);
//tableViewer.setContentProvider(new IContentProvider());
//tableViewer.setLabelProvider(new TableLabelProvider());
CellEditor[] editors = new CellEditor[2];
//editors[0] = new TextCellEditor(table);
//editors[1] = new TextCellEditor(table);
//tableViewer.setCellEditors(editors);
//tableViewer.setCellModifier(new ICellModifier());
final Text input = new Text(s, SWT.SINGLE | SWT.BORDER);
input.setTextLimit(5);
final Button searchBtn = new Button(s, SWT.BORDER | SWT.PUSH);
searchBtn.setText("Search");
searchBtn.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e){
TableItem[] tia = table.getItems();
for(int i=0;i<tia.length;i++){
tia[i].getText();
//tia[i].setBackground(new Color(d, 129, 178, 127));
//}
}
}
});
final Button addButton = new Button(s,SWT.BORDER | SWT.PUSH);
addButton.setText("Add Row");
addButton.setToolTipText("for addind a new row");
addButton.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event arg0) {
TableEditor te = new TableEditor(table);
te.grabHorizontal = true;
te.grabVertical = true;
te.getItem();
TableItem ti = table.getItem(0);
ti.getText();
}
});
s.open();
while (!s.isDisposed()) {
if (!d.readAndDispatch())
d.sleep();
}
d.dispose();
}
public Vector rowToAdd() {
Vector defaultRow = new Vector();
defaultRow.add("column1");
defaultRow.add("column1");
return defaultRow;
}
public static void main(String[] argv){
new TableShellExample();
}
}

这是一个简单的工作示例，说明如何在按下按钮时向表中添加项目：
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
RowLayout layout = new RowLayout(SWT.VERTICAL);
layout.fill = true;
shell.setLayout(layout);
shell.setSize(200, 200);
final Table table = new Table(shell, SWT.BORDER | SWT.MULTI);
final Text text = new Text(shell, SWT.SINGLE | SWT.BORDER);
text.setText("blahblah text");
Button button = new Button(shell, SWT.PUSH);
button.setText("Push me");
// this is the code you want
button.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
TableItem item = new TableItem(table, SWT.NONE);
item.setText(text.getText());
}
});
for (int i = 0; i < 5; i++) {
TableItem item = new TableItem(table, SWT.NONE);
item.setText("*** Item " + i + "***");
}
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
如果必须使用TableViewer系统添加项目，则需要修改传递给查看器的任何Object作为其输入。如果您使用IStructuredContentProvider作为查看者的内容提供程序，getElements方法将返回一个数组，该数组继续成为表的行。要在更改输入后更新它，只需致电viewer.refresh()

简单的学习方法：在表格和选定的行中添加文本字段记录 可以使用SWT在文本字段上显示
package rcp_demo.Views;
import org.eclipse.swt.widgets.Composite;
public class TaskView extends ViewPart {
public static Table table;
public static TableViewer tableViewer;
public static TableItem std_item;
private Text txt_1,txt_2,txt_3;
Student stud=new Student();
List<Student> std=new ArrayList<Student>();
public TaskView() {
setTitleImage(SWTResourceManager.getImage("D:\\Icon\\Tasksview.png"));
}
@Override
public void createPartControl(Composite parent) {
parent.setLayout(null);
//Three Text
txt_1 = new Text(parent, SWT.BORDER);
txt_1.setBounds(21, 10, 76, 19);
txt_2 = new Text(parent, SWT.BORDER);
txt_2.setBounds(119, 10, 76, 19);
txt_3 = new Text(parent, SWT.BORDER);
txt_3.setBounds(222, 10, 76, 19);
tableViewer = new TableViewer(parent, SWT.BORDER | SWT.FULL_SELECTION);
table = tableViewer.getTable();
//how to pass values of a selected row from tableviewer to a text box in SWT
table.addListener(SWT.Selection, new Listener()
{

public void handleEvent(Event e) {
Table table = (Table) e.widget;
TableItem item = table.getItem(table.getSelectionIndex());
/* Fill the texts */

{
txt_1.setText(item.getText(col));

}
}
public TableViewer getViewer() {
