这样为什么不对？

为什么只有一个值，一行值怎么取？

faint，又忘记了。这两行是不用的：
Rectangle rect = jTable.getCellRect(row, col, false);
jTable.repaint(rect);
Rectangle rect = jTable.getCellRect(row, col, false);
jTable.repaint(rect);

sorry,有一个地方写错了。应该是：
JTable jTable = new JTable(myTableModel);
jTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
int col = jTable.getSelectedColumn();
int row = jTable.getSelectedRow();
Object obj = jTable.getValueAt(row, col);
String value = obj == null? "":obj.toString();
System.out.println(value);
Rectangle rect = jTable.getCellRect(row, col, false);
jTable.repaint(rect);
}
});
JTable jTable = new JTable(myTableModel);
jTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
int col = jTable.getSelectedColumn();
int row = jTable.getSelectedRow();
Object obj = jTable.getValueAt(row, col);
String value = obj == null? "":obj.toString();
System.out.println(value);
Rectangle rect = jTable.getCellRect(row, col, false);
jTable.repaint(rect);
}
});
