JTable实现Integer和Double数据类型的列，只能输入符合标准的值

如下图，该列的数据类型为Integer类，则不能输入Double和字符串类型的内容

如何设定表格的列的类型？

public DefaultTableModel tableModelInstance() {
         
        return new DefaultTableModel() {
            private static final long serialVersionUID = 1L;
 
            @Override
                        //返回的数据类型是什么，代表该列是什么类型
            // 重写该方法可使排序根据class的类型排序
            public Class<?> getColumnClass(int column) {
                if ((column >= 0) && (column < getColumnCount())) {
                    if (getRowCount() > 1) {
                        Object valueAt = getValueAt(0, column);
                        return valueAt == null ? Object.class : valueAt.getClass();
                    }
                }
                return super.getColumnClass(column);
            }
        };
         
    }

tableModel  = tableModelInstance(); 
        for (int i = 0; i < columnName.size(); i++) {
            String s = columnName.get(i);
            tableModel.addColumn(s);
            columnMap.put(s, i);
        }
 
        table.setModel(tableModel);
