jQuery dataTables筛选器与子行组合时不工作

我正在使用dataTables插件，并重新使用我在另一个页面上的代码来选择过滤一个特定列。当这个未能正确过滤时，我感到困惑，因为它与我以前使用的代码相同

经过检查，我现在才发现原因是使用数据表的子行-

HTML

在重置故障过滤器后选择后，过滤器不会重置

奇怪的是，如果我使用上一列$col4_filter.change函数{fnFilterColumn2；}；那么它会因为某种原因而起作用

---

我猜列插入会弄乱过滤器，因为列的索引已关闭。

抱歉，刚刚意识到我的错误是什么

function fnFilterColumn(i) {

    oTable.fnFilter($('#col4_filter').val(), i);  // hard-coding selector
}

$("#col4_filter").change( function() { fnFilterColumn(4); }); // add 1 to the column index to account for dynamically added column

---

我在查找错误的过程中被搞得一团糟，我忘了，当我更改列索引时，fnFilterColumn将查找一个不存在的元素值以进行筛选。

您可以尝试我的yadcf插件，但它没有在表中与子行一起测试。谢谢，如果我没有任何进展，我会尝试一下。
