table增删——LH（勾选项添加）
table增删——LH（勾选项添加）
实现：
1、添加，通过勾选某些选项进行添加，已有值则仅弹出对话框提醒，不进行重复添加
2、删除，点击table的某行，在进行删除，删除前询问是否确认删除
3、查找文件，filechoose
4、设置table的可编辑性，如全部不可编辑，或某几列不可编辑
包括：
class OptPanel 主面板
class Content 将添加的内容作为一个类进行构造
public class CheckDefaultModel extends DefaultTableModel 构造table
public class TableHeaderRender implements TableCellRenderer 表头的全选功能
class Test 测试
class OptPanel 主面板
