Adding rows to a JTable
提问by Saiyine
We have a simple project where we read data from a socket and we want to populate a table with the coming data, but we can't find a way to add rows to a yet created JTableobject, we can only find how to add rows at creation time of the table.
我们有一个简单的项目，我们从套接字读取数据，我们想用即将到来的数据填充一个表，但是我们找不到向尚未创建的JTable对象添加行的方法，我们只能找到如何添加行表的创建时间。
Is it possible to add rows dynamically to a JTable, or there is a better alternative object to deal with this way of showing data?
是否可以将行动态添加到 a JTable，或者有更好的替代对象来处理这种显示数据的方式？
EDIT: Thanks a lot for your answers.
编辑：非常感谢您的回答。
All three of them look very promising, but I have to choose only one and I think the best is Guillaume's.
他们三个看起来都很有前途，但我只能选择一个，我认为最好的是纪尧姆的。

You should create a custom TableModel. A JTabledoesn't actually store the rows, it always delegates that to a TableModel. To help you implementing it, you should make use of AbstractTableModel. Don't forget to call fireTableRowsInserted()every time you add rows. For better performances if you add a lot of rows, try to batch the updates and add many rows at a time.
您应该创建一个自定义TableModel. AJTable实际上并不存储行，它总是将其委托给 a TableModel。为了帮助您实现它，您应该使用AbstractTableModel. fireTableRowsInserted()每次添加行时不要忘记调用。如果添加很多行，为了获得更好的性能，请尝试批量更新并一次添加多行。

Once you start dynamically adding and removing elements from a JTable, you really need to start using a TableModel.
一旦开始在 JTable 中动态添加和删除元素，您就真的需要开始使用 TableModel。
See the Java Tutorialfor more details.

If you use the default table model for a JTable then you can add rows with following code
如果您对 JTable 使用默认表模型，则可以使用以下代码添加行
if ( dest+1 < table.getRowCount()-1 )
( (DefaultTableModel) table.getModel() ).insertRow(dest+1, getValuesForNewRow());
else
( (DefaultTableModel) table.getModel() ).addRow(getValuesForNewRow());
