将数据推送到Excel的Node.js无效

Question

您好我正在尝试将数据从我的查询数组推送到excel中，但只显示标题，但结果正在被推送。当我做一个console.log以查看是否会被推送时，它表示未定义。关于为什么的任何想法？

示例代码：

var excel_data=[];
excel_data.push=(['Source', 'Count of thing 1', 'Count of thing 2', 'Count of thing 3']);
var database = new database(config);
var query_array = ['select count(*) as count_of_thing1 from table1', 'select count(*) as count_of_thing2 from table2', 'select count(*) as count_of_thing3 from table3'];

query_array.forEach(q => {
   database.query(q)
   .then(rows => {
        _.each(rows, function(row){
            excel_data.push([row.count_of_thing1, row.count_of_thing2, row.count_of_thing3]);
});
})
var wb = XLSX.utils.book_new();
 var ws_name = "Query_Results";
 var wscols = [ {width: 15} ];
 var wsrows = [];
 var ws = XLSX.utils.aoa_to_sheet(excel_data, {cellDates:true});
 ws['!cols'] = wscols;
 ws['!rows'] = wsrows;
 XLSX.utils.book_append_sheet(wb, ws, ws_name);
 var filenames = [
   ['mysql.xlsx', {bookSST:true}],
   ['mysql.csv', {bookSST:true}],
 ];
 filenames.forEach(function(r) {
   XLSX.writeFile(wb, r[0], r[1]);
   XLSX.readFile(r[0]);
 });

});
