Style

Jspreadsheet is constructed using real DOM elements, which allows you to apply CSS directly to the cells. However, when you use external styling, there is no internal tracking, history, or persistence. Therefore, Jspreadsheet offers settings and methods to manage the internal style programmatically.

What is new Jspreadsheet now features a global style property at the spreadsheet level, enabling the reuse of styles across different worksheets and cells. Additionally, the latest version allows for the application of CSS styles to entire rows or columns through Excel-like syntax, such as A:A or 1:1.

Documentation

Methods

You can manage the spreadsheet cell style with the following methods.

Method	Description
getStyle	Get style from one or multiple cells. @param {string\|null} - Cell identification or null for the whole table. @param {boolean?} - Return the indexes of the global style. `getStyle(cellName: String \| null, onlyIndexes?: Boolean)`
setStyle	Set a single cell style by name, or set the style for multiple cells. @param {String\|Object} - ID of a cell or an object with multiple cells and the style definitions. @param {String?} property - Style property @param {String?} value - Style value @param {Boolean?} forceOverwrite - true to overwrite the existing CSS. `setStyle: (cell: string \| object, property?: string, value?: string, forceOverwrite?: boolean) => void;`
resetStyle	Reset the style for one or multiple cells @param {string\|string[]} - String to identify a cell or an array of cell identifications (A1, A2... etc) `resetStyle(cellName: String \| String[])`

Events

Spreadsheet style related events.

Event	Description
onchangestyle	`onchangestyle(worksheet: Object, newValue: Object, oldValue: Objectd) : void` The method will return an object with the cells and the properties applied.

Initial Settings

The following property is available through the initialization of the online spreadsheet.

Property	Description
Worksheet level
style: object	Each object property corresponds to a cell name and range, with the value representing either a CSS string or ID for the global style.
Spreadsheet level
style: string[]	The global style definition is an array of CSS strings to generate the CSS classes that will be used across all worksheets.

Examples

Style in the worksheet level

Create a data grid with the style definitions on the worksheet level.

Programmatic updates

Defining cell style during initialization and changing it programmatically can be achieved using the following example.

Even after the initialization, the cell style can still be managed programmatically through the getStyle and setStyle methods.

External CSS styling

The following example uses global CSS to apply a background color on even rows.

<div id="spreadsheet"></div>

<script>
// Create the spreadsheet
jspreadsheet(document.getElementById('spreadsheet'), {
    worksheets: [{
        minDimensions: [8, 10],
    }]
});
</script>
<style>
#spreadsheet tbody tr:nth-child(even) {
    background-color: #eee;
}
</style>

Releases notes

Differences from version 9

Style properties	Now JSS has the spreadsheet.style array of strings is used to declare the style strings, and the worksheet style property is used to assign those styles to the cells.
setStyle	The setStyle method adds style properties on top of the existing ones, but you can also use the fourth argument, forceOverwrite, to replace a current style with a new one.
Initialize style to range of cells	Specifying a new worksheet style using an Excel-like range of cell notation is possible.
