public class JTable_main extends JFrame {
private int rows=3, cols=5;
private Object[] rowData = new Object[cols];

private DefaultTableModel model = new DefaultTableModel();
private JTable table = new JTable(model);

public JTable_main() {
for(int c=0; c < cols; ++c){
model.addColumn("Column " + Integer.toString(c));
}
for(int r=0; r < rows; ++r) {
for(int c=0; c < cols; ++c) {
rowData[c] = "(" + r + "," + c + ")";
}
model.addRow(rowData);
}
getContentPane().add(new JScrollPane(table),BorderLayout.CENTER);
getContentPane().add(new ControlPanel(),BorderLayout.NORTH);
}

public static void main(String args[]) {
GJApp.launch(new JTable_main(),"Using DefaultTableModel",150,150,600,350);
}

class ControlPanel extends JPanel {
private JButton rowButton = new JButton("Add Row"),colButton = new JButton("Add Column");

public ControlPanel() {
add(rowButton);
add(colButton);

rowButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int rowCount = model.getRowCount();
int colCount = model.getColumnCount();

if(colCount > rowData.length) rowData = new Object[colCount];

for(int c=0; c < colCount; ++c) {

}
model.addRow(rowData);
}
});
colButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int colCount = model.getColumnCount();
model.addColumn("Column " + colCount);

// Bug: the call to sizeColumnsToFit()
// should not be necessary
table.sizeColumnsToFit(-1);
}
});
}
}
}
class GJApp extends WindowAdapter {

statusArea.setBorder(BorderFactory.createEtchedBorder());
statusArea.setLayout(new FlowLayout(FlowLayout.LEFT,0,0));
statusArea.add(status);
status.setHorizontalAlignment(JLabel.LEFT);

f.setDefaultCloseOperation(
WindowConstants.DISPOSE_ON_CLOSE);

if(propertiesFilename != null) {
resources = ResourceBundle.getBundle(
propertiesFilename, Locale.getDefault());
}

f.addWindowListener(new WindowAdapter() {

System.exit(0);
}
});
}

return statusArea;
}

status.setText(s);
}
static Object getResource(String key) {

return resources.getString(key);
}
return null;
}
}

Answer 2

有3种方法：
Object[][] cellData = {
{"row1-col1", "row1-col2"},
{"row2-col1", "row2-col2"}};

String[] columnNames = {"col1", "col2"};

一、 JTable table = new JTable(cellData, columnNames);
二、int rows = 10;
int cols = 10;
table = new JTable(rows, cols);
三、Vector rowData = new Vector();
for (int i=0; i<cellData.length; i++) {
Vector colData = new Vector(Arrays.asList(cellData[i]));
rowData.add(colData);
}
Vector columnNamesV = new Vector(Arrays.asList(columnNames));

JTable table = new JTable(rowData, columnNamesV);

有对的.
