要达到的效果：

说明：点击导出按钮，实现表格的excel导出。

使用的插件：

nodeExcel = require(‘excel-export’)

代码：

sql.saveTidExcelFile = function(req, res){
  var id = req.params['id'];
  var filename = "The_"+id+"_group_randomOut";
  if(id.split('.').length>1){
    var trid = id;
    var selSQL = "select *from csp_random_allocated_results where trid='"+trid+"'order by gid, CAST(cindex as SIGNED) asc"
    var nameSql ="select gid, gname from csp_group where gid in (select gid from csp_random_allocated_results where trid = '"+trid+"')";
    csp.db.query(nameSql, function(err, nameData){
      if(!err){
        var name = nameData;
        csp.db.query(selSQL,function(err,data){
          if(!err){
            var tidRandomData = data;
            var cols = []
            var rows = []
            var titles = [
                "序号","证券代码","证券名称","心愿数量","实际分券数量","所属小组"
            ]

              //规定列数和类别
