本文整理了Java中org.eclipse.swt.widgets.Table类的一些代码示例，展示了Table类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Table类的具体详情如下：
包路径：org.eclipse.swt.widgets.Table
类名称：Table

Table介绍

[英]Instances of this class implement a selectable user interface object that displays a list of images and strings and issues notification when selected.

The item children that may be added to instances of this class must be of type TableItem.

Style VIRTUAL is used to create a Table whose TableItems are to be populated by the client on an on-demand basis instead of up-front. This can provide significant performance improvements for tables that are very large or for which TableItem population is expensive (for example, retrieving values from an external source).

Here is an example of using a Table with style VIRTUAL: ``

final Table table = new Table (parent, SWT.VIRTUAL | SWT.BORDER); 
table.setItemCount (1000000); 
table.addListener (SWT.SetData, new Listener () { 
public void handleEvent (Event event) { 
TableItem item = (TableItem) event.item; 
int index = table.indexOf (item); 
item.setText ("Item " + index); 
System.out.println (item.getText ()); 
} 
});

Note that although this class is a subclass of Composite, it does not normally make sense to add Control children to it, or set a layout on it, unless implementing something like a cell editor.

Styles: SINGLE, MULTI, CHECK, FULL_SELECTION, HIDE_SELECTION, VIRTUAL, NO_SCROLL Events: Selection, DefaultSelection, SetData, MeasureItem, EraseItem, PaintItem

Note: Only one of the styles SINGLE, and MULTI may be specified.

IMPORTANT: This class is not intended to be subclassed.
[中]此类的实例实现了一个可选的用户界面对象，该对象显示图像和字符串的列表，并在选中时发出通知。
可以添加到此类实例的项子项必须是[$0$]类型。
样式VIRTUAL用于创建一个Table，其TableItem由客户按需填充，而不是预先填充。这可以为非常大的表或TableItem填充非常昂贵的表（例如，从外部源检索值）提供显著的性能改进。
下面是一个使用Table和样式VIRTUAL：``的示例

final Table table = new Table (parent, SWT.VIRTUAL | SWT.BORDER); 
table.setItemCount (1000000); 
table.addListener (SWT.SetData, new Listener () { 
public void handleEvent (Event event) { 
TableItem item = (TableItem) event.item; 
int index = table.indexOf (item); 
item.setText ("Item " + index); 
System.out.println (item.getText ()); 
} 
});

请注意，尽管该类是Composite的子类，但通常情况下，向其添加Control子类或在其上设置布局是没有意义的，除非实现类似于单元编辑器的功能。
样式：单、多、检查、完整选择、隐藏选择、虚拟、无滚动事件：选择、默认选择、设置数据、测量项、擦除项、绘制项
注意：只能指定一种样式“单”和“多”。
重要提示：这个类不是子类。
