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 |
| :————– | :————- | :————- |
| fill | patternType | "solid" or "none"
| | fgColor | COLOR_SPEC
| | bgColor | COLOR_SPEC
| font | name | "Calibri" // default
| | sz | "11" // font size in points
| | color | COLOR_SPEC
| | bold | true or false
| | underline | true or false
| | italic | true or false
| | strike | true or false
| | outline | true or false
| | shadow | true or false
| | vertAlign | true or false
| 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
| | | "m/dd/yy" // string a date format using Excel’s format notation
| alignment | vertical | "bottom" or "center" or "top"
| | horizontal | "bottom" or "center" or "top"
| | wrapText | true or ` false
| | readingOrder | 2 // for right-to-left
| | textRotation | Number from 0 to 180 or 255 (default is 0)
| | | 90 is rotated up 90 degrees
| | | 45 is rotated up 45 degrees
| | | 135 is rotated down 45 degrees
| | | 180 is rotated down 180 degrees
| | | 255 is special, aligned vertically
| 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 or false
| | diagonalDown | true or false`
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 forfill.bgColor
BORDER_STYLE: Border style is a string value which may take on one of the following values:
thinmediumthickdottedhairdashedmediumDasheddashDotmediumDashDotdashDotDotmediumDashDotDotslantDashDot
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
