The TableModelbehind the JTable handles all of the data behind the table. In order to add and remove rows from a table, you need to use a DefaultTableModel
TableModelJTable的后面处理表后面的所有数据。为了在表中添加和删除行，您需要使用DefaultTableModel
To create the table with this model:
要使用此模型创建表：
JTable table = new JTable(new DefaultTableModel(new Object[]{"Column1", "Column2"}));
To add a row:
添加一行：
DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{"Column 1", "Column 2", "Column 3"});
You can also remove rows with this method.
您还可以使用此方法删除行。

用：
DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
// Create a couple of columns

Use
用
DefaultTableModel model = (DefaultTableModel) MyJTable.getModel();
Vector row = new Vector();
row.add("Enter data to column 1");
row.add("Enter data to column 2");
row.add("Enter data to column 3");
model.addRow(row);
get the model with DefaultTableModel modelName = (DefaultTableModel) JTabelName.getModel();
获取模型 DefaultTableModel modelName = (DefaultTableModel) JTabelName.getModel();
Create a Vector with Vector vectorName = new Vector();
创建一个向量 Vector vectorName = new Vector();
add so many row.addas comumns
添加row.add尽可能多的comumns
add soon just add it with modelName.addRow(Vector name);
尽快添加只需添加它 modelName.addRow(Vector name);

For the sake of completeness, first make sure you have the correct import so you can use the addRowfunction:
为了完整起见，首先确保您有正确的导入，以便您可以使用该addRow功能：
import javax.swing.table.*;
Assuming your jTable is already created, you can proceed and create your own add row method which will accept the parameters that you need:
假设您的 jTable 已经创建，您可以继续并创建您自己的 add row 方法，该方法将接受您需要的参数：
public void yourAddRow(String str1, String str2, String str3){
DefaultTableModel yourModel = (DefaultTableModel) yourJTable.getModel();
yourModel.addRow(new Object[]{str1, str2, str3});
}
