## Cell Style

Cell styles are specified by a style object that roughly parallels the OpenXML structure. The style object has five
top-level attributes: `fill`, `font`, `numFmt`, `alignment`, and `border`.

| Style Attribute | Sub Attributes | Values                                                                                        |

**COLOR_SPEC**: Colors for `fill`, `font`, and `border` are specified as objects, either:

- `{ auto: 1}` specifying automatic values
- `{ rgb: "FFFFAA00" }` specifying a hex ARGB value
- `{ theme: "1", tint: "-0.25"}` specifying an integer index to a theme color and a tint value (default 0)
- `{ indexed: 64}` default value for `fill.bgColor`

**BORDER_STYLE**: Border style is a string value which may take on one of the following values:

- `thin`
- `medium`
- `thick`
- `dotted`
- `hair`
- `dashed`
- `mediumDashed`
- `dashDot`
- `mediumDashDot`
- `dashDotDot`
- `mediumDashDotDot`
- `slantDashDot`

Borders for merged areas are specified for each cell within the merged area. So to apply a box border to a merged area of 3x3 cells, border styles would need to be specified for eight different cells:

- left borders for the three cells on the left,
- right borders for the cells on the right
- top borders for the cells on the top
- bottom borders for the cells on the left

## Dependencies

This library uses [file-saver](https://www.npmjs.com/package/file-saver) and [xlsx](https://www.npmjs.com/package/xlsx) and using [json-loader](https://www.npmjs.com/package/json-loader) will do the magic for you.

```javascript
///webpack.config.js
vendor: [
        .....
        'xlsx',
        'file-saver'
],
.....
node: {fs: 'empty'},
externals: [
    {'./cptable': 'var cptable'},
    {'./jszip': 'jszip'}
 ]
