jQuery数据表属性columnDefs如何工作？

Question

I have confusion on jQuery Datatables , I saw few code where datatables use columndefs , I don't understand columndefs attributes [targets] and [orderable] actually what they do.

Here is a sample code.

"columnDefs":[  
  {  
    "targets":[0, 3, 4],  
    "orderable":false,  
  },  
],  

Answer 1

在这种特殊情况下，对索引为0,3和4的列禁用排序
