描述
Add a terminal UI for Luckysheet, probably using blessed library: https://github.com/chjj/blessed (if your API is in nodeJS; works, but frozen), or https://github.com/jquast/blessed (if your API can be bound to Python; works, and is actively maintained), or use mighty old ncurses (in C; for the bold...). This would of course use the existing Luckysheet API.
