如何在已经存在的记录的json datatable之上添加一行 [英] how to add a new row in top of a json datatable with already existing records

问题描述

我正在尝试在datatable的顶部添加一行，显示列amount的总和。我使用json datatable（jquery plugin）列表显示datatable。我如何将这行添加到现有行的datatable之上？

解决方案

我认为这段代码可以帮助你

  var json ='{uid：user123，firstName：User，lastName：Theuser}' ; 
 userTable.fnAddData（json）; 
  

请参阅以下链接

或

在从表中获取数据的同时也将其作为第一行

I am trying to add a row in top of a datatable which shows sum of a column "amount".I am using json datatable(jquery plugin) list to display datatable. How can i add this row in top of datatable with existing rows?

解决方案

I think this code will help you

var json = '{ "uid": "user123", "firstName": "User", "lastName": "Theuser" }';
userTable.fnAddData(json);

Please refer the below link

Or

At the time of fetching data from table take sum also and make it as first row
