tableView
如果用到表格的话，我们就要用到tableView
1.使用QtDesign绘制出tableView_1，就可以显示行和列，后将其转化为py文件：
2.转化为py文件后，我们更改上文提到的model，
将listModel更改为tableModel，将ListView更改为tableView_1
self.table_model = demo_model.TableModel(self.tableView_1)我们生成一个Model，把它放在View的当作它的子物体，self.tableView_1其实是一个子物体，是一个高级化的列表
tableView与listView不同的是，它不仅需要行也需要列

columnCount rowCount为定义列数和行数，其中行数一般为固定数字，为避免刷新慢，
self.table_data需要一个二维的列表
data函数中需要得到单元格的索引，来访问列表里的数据
增加数据：
需要使用insertRow
在insertRow中，需要先定义开始插入，结束之后要定义endIsertRows
删除一行：
需要使用removeRow
