## Development model

### Requirements
[Node.js](https://nodejs.org/en/) Version >= 6 

### Installation
```shell
npm install
npm install gulp -g
```

### Development
```shell
npm run dev
```

### Package
```shell
npm run build
```

## Steps for usage

### First step

There are two ways to introduce dependencies

#### CDN
```html
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/css/pluginsCss.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/plugins.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/css/luckysheet.css' />
<script src="https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/js/plugin.js"></script>
<script src="https://cdn.jsdelivr.net/npm/luckysheet/dist/luckysheet.umd.js"></script>
```

Note that `https://cdn.jsdelivr.net/npm/luckysheet/dist/luckysheet.umd.js` will pull the latest luckysheet code. If you want to specify the luckysheet version, please add the version number after the luckysheet , Such as: `https://cdn.jsdelivr.net/npm/luckysheet@2.0.0/dist/luckysheet.umd.js`

If it is not convenient to access jsdelivr.net, you can also import it locally

#### Import locally
After `npm run build`, all files in the `dist` folder are copied to the project directory
```html
<link rel='stylesheet' href='./plugins/css/pluginsCss.css' />
<link rel='stylesheet' href='./plugins/plugins.css' />
<link rel='stylesheet' href='./css/luckysheet.css' />
<script src="./plugins/js/plugin.js"></script>
<script src="./luckysheet.umd.js"></script>
```
### Second step
Specify a table container
```html
<div id="luckysheet" style="margin:0px;padding:0px;position:absolute;width:100%;height:100%;left: 0px;top: 0px;"></div>
```
### Third step
Create a table
```javascript
<script>
    $(function () {
        //Configuration item
        var options = {
            container: 'luckysheet' //luckysheet is the container id
        }
        luckysheet.create(options)
    })
</script>
```

## Structure

### Format

The data format of a complete Luckysheet table file is: luckysheetfile, a table file contains several sheet files, corresponding to excel sheet0, sheet1, etc.

An example of a Luckysheet file is as follows, the table contains 3 sheets:`
luckysheetfile = [{sheet1 settings}, {sheet2 settings}, {sheet3 settings}]`
Equivalent to 3 sheets of excel

![excel sheet](/LuckysheetDocs/img/excel.png)

An example of a sheet in the file is as follows:
```javascript
luckysheetfile[0] = 
{
	"name": "Cell", //Worksheet name
	"color": "", //Worksheet color
	"config": {}, //Table row height, column width, merged cells, borders, hidden rows and other settings
	"index": "0", //Worksheet index
	"chart": [], //Chart configuration
	"status": "1", //Activation status
	"order": "0", //The order of the worksheet
	"hide": 0,//whether to hide
	"column": 18, //Number of columns
	"row": 36, //number of rows
	"celldata": [], //Original cell data set
	"visibledatarow": [], //The position of all rows
	"visibledatacolumn": [], //The position of all columns
	"ch_width": 2322, //The width of the worksheet area
	"rh_height": 949, //The height of the worksheet area
	"scrollLeft": 0, //Left and right scroll bar position
	"scrollTop": 315, //Up and down scroll bar position
	"luckysheet_select_save": [], //selected area
	"luckysheet_conditionformat_save": {},//Conditional format
	"calcChain": [],//Formula chain
	"isPivotTable":false,//Whether to pivot table
	"pivotTable":{},//Pivot table settings
	"filter_select": null,//Filter range
	"filter": null,//Filter configuration
	"luckysheet_alternateformat_save": [], //Alternate colors
	"luckysheet_alternateformat_save_modelCustom": []//Customize alternate colors
}
```
### View method
View in chrome's console
`luckysheet.getluckysheetfile()`
You can see the complete settings
`[{shee1}, {sheet2}, {sheet3}]`
