Customize Range Groups

SpreadJS supports the customization of range groups in order to enhance the appearance of the worksheet while also making it easy for users to organize and manipulate data in an efficient way.

You can set the custom background color, border color outline area, background color of the icon, font color of number and +/-, background image of the number and +/-, border color of the button, line color, line width and dot color as depicted in the below image:

Shared below is a table that lists the attributes of range groups that can be customized along with the corresponding CSS class and the CSS attribute:

Range Group Attribute	CSS class Name	CSS Attribute	Additional Comments
Backcolor of outline area	`gc-group`	`background-color`
Border color of outline area	`gc-group`	`color`
Backcolor of icon	`gc-group-box`	`background-color`
Font color of number and +/-		`color`
Border color of button		`border-color`	This attribute will use the `border-top-color` from the CSS and will ignore any other border color.
BackgroundImage of number and +	`gc-group-box-expand`	`background-image`	The default border color and the background color are transparent when the `background-image` is set by the user. If no background image is set, it will use the style defined in the `gc-group-box`, by default. If the defined CSS includes more than one background image, only the first background image will take effect.
BackgroundImage of number and -	`gc-group-box-collapsed`	`background-image`	The default border color and the background color is transparent when the `background-image` is set by the user. If no background image is set, it will use the style defined in the `gc-group-box`, by default. If the defined CSS includes more than one background image, only the first background image will take effect.
Line color	`gc-group-line`	`border-color`	This attribute will use the `border-top-color` from the CSS and will ignore any other border color.
Line Width	`gc-group-line`	`border-width`	This attribute will use the border-top-width from the CSS and will ignore any other border color.
Dot Color	`gc-group-dot`	`color`

The following code sample shows to customize the attributes of range groups while working with spreadsheets:

    .gc-group {
        background-color: rgb(180, 211, 230);
        color: #999999;
        border-width: 0px;
        border-style:solid;
    }
    .gc-group-box {
        background-color: #fff;
        color: rgb(8, 154, 245);
        border-color:rgb(32, 158, 241);
    }
    .gc-group-line{
        border-width:2px;
        border-style:solid;
        border-color:rgb(137, 199, 243);
    }
    .gc-group-dot{
        color:blue;
    }

Note: Customization of more than one distinct CSS for different spreadsheet elements is not possible on the same page.
