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

    }

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.
