SWT可以为您做到这一点。当您使用SWT.VIRTUAL样式标志时，仅当滚动到视图时才创建项目。方法如下：
public static void main( String[] args ) {
Display display = new Display();
Shell shell = new Shell( display );
shell.setLayout( new FillLayout() );
final Table table = new Table( shell, SWT.VIRTUAL );
table.setItemCount( 10000 );
table.addListener( SWT.SetData, new Listener() {
public void handleEvent( Event event ) {
TableItem item = (TableItem)event.item;
item.setText( "Item " + table.indexOf( item ) );
}
} );
shell.setSize( 300, 500 );
shell.open();
while( !shell.isDisposed() ) {
if( !display.readAndDispatch() ) {
display.sleep();
}
}
display.dispose();
}
