@ -428,6 +428,111 @@ The exported `write` and `writeFile` functions accept an options argument:
third-party readers. Excel itself does not usually write cells with type `d`
so non-Excel tools may ignore the data or blow up in the presence of dates.
## Cell Styles
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 |
| :-------------- | :------------- | :------------- | :----- |
| fill | patternType | 'solid' or 'none' |
| | fgColor | COLOR_SPEC
| | bgColor | COLOR_SPEC
| font | name | "Calibri" // default
| | sz | "11" // font size in points
| | color | COLOR_SPEC
| numFmt | | "0" // integer index to built in formats, see StyleBuilder.SSF property
| | | "0.00%" // string matching a built-in format, see StyleBuilder.SSF
| | | "0.0%" // string specifying a custom format
| | | "0.00%;\\(0.00%\\);\\-;@" // string specifying a custom format, escaping special characters
| alignment | vertical | "bottom"||"center"||"top"
| | horizontal | "bottom"||"center"||"top"
| border | top | { style: BORDER_STYLE, color: COLOR_SPEC }
| | bottom | { style: BORDER_STYLE, color: COLOR_SPEC }
| | left | { style: BORDER_STYLE, color: COLOR_SPEC }
| | right | { style: BORDER_STYLE, color: COLOR_SPEC }
| | diagonal | { style: BORDER_STYLE, color: COLOR_SPEC }
| | diagonalUp | true||false
| | diagonalDown | true||false
**COLOR_SPEC** Colors for `fill`, `font`, and `border` are specified as objects, either:
* `{ 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** are piped directly to XML and may take on one of the following values:
* `thin`
*`medium`
*`thick`
*`dotted`
* `hair`
* `dashed`
* `mediumDashed`
* `dashDot`
* `mediumDashDot`
* `dashDotDot`
* `mediumDashDotDot`
* `slantDashDot`
