Javascript 如何动态地将行添加到jquery数据表中，并优化要显示的列？
我想在pageload上的数据表中动态添加行 我想将来自datatable的ajax请求的数据分成两行（如果条件为true，则第二行将动态添加到该行） 下面是一个例子，应该更清楚地说明这一点Javascript 如何动态地将行添加到jquery数据表中，并优化要显示的列？,javascript,jquery,html,datatable,Javascript,Jquery,Html,Datatable,我想在pageload上的数据表中动态添加行 我想将来自datatable的ajax请求的数据分成两行（如果条件为true，则第二行将动态添加到该行） 下面是一个例子，应该更清楚地说明这一点 <table> <thead> <tr> <td>Name</td> <td>City</td> <td>Work</td> <td>Address</td&

到目前为止，你能详细说明一下吗？为什么服务器端不根据条件追加行？我不知道是否可以从服务器端追加行？我正在使用asp.net MVCYou注意到这是一个服务器端表。因此，服务器端代码应该检查条件，然后在返回Json之前向结果集中添加一行。您必须发布服务器端代码，我才能帮助您添加行，但它应该是相当直接的。请注意，字段不同，但结果应该相同。只需将任意四个字段附加到新行即可。
