模型更新时JTable不更新

Question

public Main() {
        initComponents();
        current_map = new Map();
        current_map.authors.add(new Author("New Author"));
        author_model = new AuthorModel(current_map.authors);
        jTable1.setModel(new AuthorModel(current_map.authors)); <---This is the mistake
    }   
...     



    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        author_model.authors.add(new Author("New Author"));
        author_model.fireTableRowsInserted(author_model.authors.size(), author_model.authors.size());
    }

我现在迷路了。

Answer 1

该表初始化为：

jTable1.setModel(new AuthorModel(current_map.authors));

但是当单击该按钮时，您将修改变量author_model:

author_model.authors.add(new Author("New Author"));

表的初始化应该是

jTable1.setModel(author_model);
