Adding an Array to JTable in Java
提问by Jonas
Since you create the JTablewith an matrix for data and array for the columns I figured there should be a way to after created the JTableadding an array (row). Or how is it meant to add a row with Strings?
由于您JTable为数据创建了矩阵，为列创建了数组，我认为应该有一种方法可以在创建后JTable添加数组（行）。或者用字符串添加一行是什么意思？
Thanks!
谢谢！

You cannot add to a JTable directly, you have to get the underlying TableModel. You get this by calling JTable.getModel(). TableModel is an interface, in a standard JTable it's implementation is DefaultTableModel. So you have to cast the underlying TableModel to a DefaultTableModel, and then you can apply DefaultTableModel.addRow( Object[] ). (You do, of course, check that the cast is safe and all that).
您不能直接添加到 JTable，您必须获得底层的 TableModel。您可以通过调用JTable.getModel(). TableModel 是一个接口，在标准 JTable 中它的实现是 DefaultTableModel。因此，您必须将底层 TableModel 强制转换为 DefaultTableModel，然后才能应用DefaultTableModel.addRow( Object[] ). （当然，您确实要检查演员表是否安全等等）。

To change the data displayed by the JTable, you need to go through the TableModel.
要更改 显示的数据JTable，您需要通过TableModel。
Have a look at the JTable.getModel()method and the methods in the TableModelinterface.
看看JTable.getModel()方法和TableModel接口中的方法。

you can add/insert row in JTable like this way
您可以像这样在 JTable 中添加/插入行
table.getModel().insertRow(table.getRowCount(),new Object[]{"hello","50"});

You can also create a class of your own which extends AbstractTableModeland implement the abstract methods. This class can also contain the array (or whichever collection or data structure you use) and the abstract methods which you implement will use this array, methods such as getValueAtand setValueAt. Then you can create a new instance of this class and set the table model of the table to this object. Adding rows to this table is now possible by adding entries/elements to the array.
您还可以创建自己的类，它扩展AbstractTableModel并实现抽象方法。此类还可以包含数组（或您使用的任何集合或数据结构），您实现的抽象方法将使用此数组，如getValueAt和setValueAt等方法。然后就可以新建这个类的实例，将表的表模型设置为这个对象。现在可以通过向数组添加条目/元素来向该表添加行。
