xlsx.js导出表格数据

 定义导出方法

export function exportExcel(table,fileName,ws_name) {

        //table ---json数据 fileName---导出的文件名   ws_name---sheet名

        //创建book

        var wb = XLSX.utils.book_new();

        // json转sheet

        var ws = XLSX.utils.json_to_sheet(table, { skipHeader:true});

        var timestamp = (new Date()).getTime();

        //sheet写入book

        XLSX.utils.book_append_sheet(wb, ws, ws_name);

        //输出

        XLSX.writeFile(wb,fileName+".xlsx");

}
