列在数据表中隐藏后索引不匹配

Question

您好，我正在使用数据表，并且根据某些业务逻辑，表中的某些列已显示或隐藏，因为我是从Java端将aoColumns作为JSon发送的，但是我面临的问题是rowCallBack函数 我正在处理隐藏列时未匹配的索引上的列

这是我操作列的方式：

$（'td：eq（0）'，nRow）.html（“” + nameTrimmed +“”）;

我的猜测是索引中不包含隐藏列，而rowCallBack只是操作该索引上可见的任何列

我不能为每种情况编写不同的rowCallBack来保持通用性 有什么方法可以将隐藏列包括在索引计数中？ 或者可以通过除索引之外的其他方式修改列。

这是代码
