我的代码在每行添加数据"中

m_patterncount-1是我的行计数器
piecetypes [0]是要插入到JTable中的样本数据.

Good day!
Guys, can you help me on how to add a data per row in my JTable?
I have here my code in "adding a data per row"

m_patterncount-1 is my row counter
piecetypes[0] is a sample data to be inserted in the JTable

String []strlist = {"Pattern Codes","Open Piece Types"};    //Column Header
DefaultTableModel model = new DefaultTableModel(null,strlist);
jtable = new javax.swing.JTable(model);

jtable.setModel(new javax.swing.table.DefaultTableModel(
    null,
    strlist
));

model.insertRow(m_patterncount-1, new Object[]{piecetypes[0]});

我只是遵循了一些教程，但仍然行不通.

如何:

public InsertRows()
{
  JFrame frame = new JFrame("Inserting rows in the table!");
  JPanel panel = new JPanel();
  String data[][] = {{"Vinod","100"},{"Raju","200"},{"Ranju","300"}};
  String col[] = {"Name","code"};
  DefaultTableModel model = new DefaultTableModel(data,col);
  JTable table = new JTable(model);
  //Insert first position
  model.insertRow(0,new Object[]{"Ranjan","50"});
  //Insert 4 position
  model.insertRow(3,new Object[]{"Amar","600"});
  //Insert last position
  model.insertRow(table.getRowCount(),new Object[]{"Sushil","600"});
  panel.add(table);
  frame.add(panel);
  frame.setSize(300,300);
  frame.setVisible(true);
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
