2020年7月23日发布

1. 发布的、用于内部测试的第一个版本主要包含如下功能：
   (1) 通过设定股票代码和起止日期来查询沪深股票分价表，并以表格形式呈现；
   (2) 在查询到数据的情况下，允许导出为Excel工作簿。
2. 优化呈现的表格形式，并设计包含筛选器，以及允许通过单击标题行进行数据排列。
3. 优化导出的Excel工作簿内容的格式。
4. 增加基本的判断逻辑，使控件展示更合理（例：股票代码不符合格式时以红色显示，并禁用查询按钮）。

1. This 1st version is released mainly for alpha testing. The app includes the following 2 primary features:
   1. Search for strike prices and volumes by the symbol, start date, and end date, and display data in a data grid.
   2. Allow exporting to Excel, if data is not null.
2. Optimise the appearance of the data grid, and include filters and sorting.
3. Optimise the format of the content of Excel files exported.
4. Add basic logic to make controls work in a reasonable way (e.g. disable the search button and change the text colour of the input box for the symbol from black to red if the format is incorrect).

Known issue：Failed to export as an Excel file in XLS format. It will be fixed in a later version. At present, you can export the data grid as an Excel file in XLSX format.
