DefaultTableModel make cell not editable JTable
提问by Dave
I have an JAVA project and want to make my JTable with a DefaultTableModel non-editable. I know a work-around to do this, called:
我有一个 JAVA 项目，想让我的 JTable 带有一个不可编辑的 DefaultTableModel。我知道一种解决方法，称为：
JTable table = new JTable(...){
public boolean isCellEditable(int row, int column){
return false;
}
};
Like said: i dont like this. This is not according the rules of my school training.
就像说：我不喜欢这个。这不符合我学校的训练规则。
Is there any way to do this? Maybe is there a good way. I hope so!
有没有办法做到这一点？或许有什么好办法。但愿如此！

You should not subclass the JTable itself, but the table model:
您不应该对 JTable 本身进行子类化，而是对表模型进行子类化：
DefaultTableModel myModel = new DefaultTableModel(...) {
@Override
public boolean isCellEditable(int row, int column) {
return false;
}
}
Or even better, don't use a DefaultTableModel, and use an AbstractTableModel that directly gets the information in your business objects rather than copying all the information from the business objects to Vectors.
或者更好的是，不要使用 DefaultTableModel，而使用 AbstractTableModel 直接获取业务对象中的信息，而不是将业务对象中的所有信息复制到 Vectors。

select Jtable , and don't forget to create table model (DefaultTableModel TableModel)
选择 Jtable ，不要忘记创建表模型（DefaultTableModel TableModel）
JTable table_1 = new JTable (TableModel){public boolean isCellEditable(int row,int column)
{switch(column){
case 4: // select the cell you want make it not editable
return false;
default: return true;}
}};
