# Mini excel app
|
||||
## _Small application covering the basic functionality of Excel_
|
||||
|
||||
The application is a SPA consisting of two screens
|
||||
- Dashboard (Create new table or open saved)
|
||||
- Excel (Excel table editing page)
|
||||
|
||||
|
||||
Technologies used in this project:
|
||||
- Typescript
|
||||
- ES6+
|
||||
- SCSS
|
||||
- Redux
|
||||
- Webpack 5
|
||||
- Jest
|
||||
|
||||
|
||||
## Implemented functionality
|
||||
- Resize table rows/columns
|
||||
- Navigation and selection of cells using the function keys (Ctrl, Shift, Arrows), or using the mouse
|
||||
- Mathematical calculations in a formula
|
||||
- Ability to add/remove columns via context menu (right mouse button)
|
||||
- Changing cell style: size, font, alignment
|
||||
- Saving to LocalStorage, also implemented the ability to delete certain tables
|
||||
