//首先给QQ：7706189
//编辑器，我在旦困JPanel上 了JTextField 和JButton
public class TextCellEditor extends javax.swing.AbstractCellEditor implements
javax.swing.table.TableCellEditor {
private JDialog parent;
private JPanel editPanel;
private JTextField editText;
private JButton editButton;
public TextCellEditor(JDialog d){
this.parent=d;
editPanel = new javax.swing.JPanel();
editButton = new javax.swing.JButton();
editText = new javax.swing.JTextField();
editButton.setText("*");
editButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
new GlossarySortDialog(parent,editText).setVisible(true);

}
});
editPanel.setLayout(new BorderLayout());
editPanel.add(editText,BorderLayout.CENTER);
editPanel.add(editButton,BorderLayout.EAST);
}
public Object getCellEditorValue() {
return editText.getText();
}
//重点：这个方法返回JPanel编辑器（包括JPanel上的其他控件）
public java.awt.Component getTableCellEditorComponent(
javax.swing.JTable table, Object value, boolean isSelected,
int row, int column) {
if (value == null)
editText.setText("");
else
editText.setText(value.toString());
//返回JPanel编辑器模睁念
return editPanel;
}
}

//=============
//表格的单元格用到了

public class TempColligateTicketDialog extends javax.swing.JDialog {
private javax.swing.JTable tableColligate;
private DefaultTableModel dTableModel;
private TextCellEditor textCell; //早悉你要用的JPanel编辑器
....
....
/**
* 初始化表格
* @param strSql
*/
private void initTable() {
Object[][] body = null;
String[] head = null;
head = new String[]{"序号", "注意事项"};

dTableModel = new DefaultTableModel(body, head) {

boolean[] canEdit = new boolean[]{
false, true
};

public boolean isCellEditable(int rowIndex, int columnIndex) {
return canEdit[columnIndex];
}
};
List list = SystemConstants.getOperationCardContent();
CardOperationStep cos = null;
if (list != null) {
for (int i = 0; i < list.size(); i++) {
cos = (CardOperationStep) list.get(i);
Object[] rowData = {i+1, cos.operationCont};
dTableModel.addRow(rowData);
}
}
tableColligate.setModel(dTableModel);
tableColligate.getColumnModel().getColumn(0).setMaxWidth(50);

//在表格的第2列加JPanel编辑器
tableColligate.getColumnModel().getColumn(1).setCellEditor(textCell);
}
....
.....
}
