使用 DbUtils 将 ResultSet 转换为 TableModel 后，JTable 将设置为可编辑。 如何让它再次不可编辑？

Question

Here is My Code for doing this`

public static void addSong(String[] fileDetail, JTable SongData_Table)
{
    try {
        con = DBConnection.getCon();
        stmt = con.createStatement();

        stmt.executeUpdate("insert into songs values (null,'" + fileDetail[0] + "', '" + fileDetail[1] + "',null,null)");
        ResultSet rs = stmt.executeQuery("select * from songs");

        TableModel model = DbUtils.resultSetToTableModel(rs);
        SongData_Table.setModel(model);

        if (con != null) {
            stmt.close();
            con.close();
        }
    } catch (SQLException e) {
        System.out.println("Error in Stmt " + e);
    }
}

Answer 1

In DbUtils.resultSetToTableModel , replace

return new DefaultTableModel(rows, columnNames);

and return a TableModel that overrides isCellEditable() :

return new DefaultTableModel(rows, columnNames){

    @Override
    public boolean isCellEditable(int row, int column) {
        return false;
    }
};

Answer 2

Variable names should NOT start with an upper case character. SongData_Table should be songDataTable .

Override the isCellEditable(...) method of the JTable, instead of the TableModel.

JTable songDataTable = new JTable()
{
    @Override boolean isCellEditatable(int row, int column)
    {
        return false;
    }
};

Answer 3

You could override the method isCellEditable:

 //instance table model
  DefaultTableModel tableModel = new DefaultTableModel() {

  @Override
  public boolean isCellEditable(int row, int column) {
   //all cells false
   return false;
   }
 };

  table.setModel(tableModel);

or....

  table.setEnabled(false);

Answer 4

using Vector Convert ResultSet to TableModel instead:

.......    
Vector column = new Vector();
column.addElement("Columnname1");
column.addElement("Columnname2");
column.addElement("Columnname3");
........
//data Vector
Vector data = new Vector();
while (rs.next()) {
Vector temp = new Vector();
temp.addElement(rs.getString(1));
temp.addElement(rs.getString(2));
 temp.addElement(rs.getString(3));
  ........      
data.addElement(temp);
}
//append to JTable
yourtable.setModel(new javax.swing.table.DefaultTableModel(data,column){

@Override
public boolean isCellEditable(int row, int column) {
   return false;
}
});
......
