JTable java.lang.ArrayIndexOutOfBoundsException 中的错误：7 >= 7

Question

我的 JTable 连接到数据库时遇到问题。只要我添加、删除或修改任何数据，table 就会正确更改。但是，在使用 Table 的过滤器搜索器之后，当我尝试添加某些内容时，table 不会显示它，直到我进行另一次搜索。更新按钮是唯一有效的。

将数据库添加到 JTable 并在我进行更改时更新它的代码：

public void show_database(){
        try {
               Class.forName("com.mysql.cj.jdbc.Driver");
               cn = (Connection)DriverManager.getConnection("jdbc:mysql://localhost:3306/modificar?zeroDateTimeBehavior=CONVERT_TO_NULL", "root", "");
               pst = (PreparedStatement)cn.prepareStatement("SELECT * FROM person");
               rs = pst.executeQuery();
               table.setModel(DbUtils.resultSetToTableModel(rs));
               
        } catch (Exception e) {
            System.out.println(e);
        }
        
    }

过滤器代码：

DefaultTableModel dtm = (DefaultTableModel)table.getModel();
 TableRowSorter<DefaultTableModel> tr = new TableRowSorter<DefaultTableModel>(dtm);
 table.setRowSorter(tr);
 int column=0;
        if (combo.getSelectedItem()=="ID"){
            column = 0;
        }
        else if(combo.getSelectedItem()=="Name"){
            column = 1;
        }
        else if(combo.getSelectedItem()=="Surname"){
            column = 2;
        }
        else if(combo.getSelectedItem()=="Adress"){
            column = 3;
        }
        tr.setRowFilter(RowFilter.regexFilter(filtertxt.getText(), column));

要删除的代码：

try {
            pst = (PreparedStatement)cn.prepareStatement("DELETE FROM person WHERE id=(?)");
            pst.setInt(1, Integer.valueOf(idtxt.getText().toLowerCase()));
            pst.executeUpdate();
            idtxt.setText("");
            JOptionPane.showMessageDialog(null, "DELETED");
        } catch (Exception e) {
        }
        show_database();

此外，当我尝试删除时，它给了我这个错误。另外，一旦我再次使用过滤器，我删除的数据就会显示出来。:

好吧，我解决了这个问题，只需将其添加到过滤器的代码中即可：

if (filter.getText().equals("")){
           table.setRowSorter(null);
       }
       else{
           tr.setRowFilter(RowFilter.regexFilter(filter.getText(), column));
       }
