How can I add title and blank rows before table while exporting to excel from angularjs?

Question

I want to export data from table into excel file, but I want to add title and few blank rows before table. Also I want to do some css for that table.

This is my code in .ts file and it works but I want to style it a little bit. I didn't find anything for my problem, but also I'm beginner in this :)

exportExcel() : void { const ws: XLSX.WorkSheet =XLSX.utils.json_to_sheet(this.excelArray);

/* generate workbook and add the worksheet */
const wb: XLSX.WorkBook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, 'Sheet1');

/* save to file */  
XLSX.writeFile(wb, this.fileName);

}

Answer 1

That package is well documented: https://www.npmjs.com/package/xlsx#writing-functions however they don't have any styling functionality.

Someone has forked the package to add styling: https://www.npmjs.com/package/xlsx-style, via the s property of a Cell Object

Answer taken from here: Create an excel file with a few styles using client side JavaScript (if possible using js-xlsx library)
