【日常收支账本】【Day04】优化编辑动账记录的操作——QTableWidget单元格设置QComboBox控件

一、项目地址

https://github.com/LinFeng-BingYi/DailyAccountBook

二、新增

1. 在表格中设置选项列表，让用户更快地编辑动账记录

1.1 功能详述

为表格中以下字段设置选项列表：

1. 需求强度（由"基本需求"更名）

温饱：基本维持生存且不铺张浪费的消费行为
小康：在温饱的基础上，可以使生活变得比较舒适的消费行为
奢华：可有可无的，或超出自身消费水平的消费行为

该属性意在于让用户更好地明白基本消费与超额消费占比，以便遏制不必要的消费行为

2. 类别（支出表、收入表）

计划在将来支持用户自定义支出或收入类别。目前写死在代码中，可以在CommonFiles/ConstArgs.py文件中修改后使用

3. 支出账户、收入账户、关联账户

计划在将来支持用户自定义账户列表。目前写死在代码中，可以在CommonFiles/ConstArgs.py文件中修改后使用

1.2 代码实现

思路分析

支出、收入、转移表格中的列名有大量重复，因此将所有列的初始化集中到一个函数中，根据列名执行对应初始化方式。同时，还要区分已存在记录的行和空白行。综上，实现了三个函数：

函数名	作用
setExistTableCell	为已存在记录的表格行设置单元格
setBlankTableCell	为表格的空白行设置单元格
getExistTableCell	获取某行记录的数据，组装成字典

代码
