0行VS columnDefs请求的未知参数“0”通吃默认内容

Question

我有一个问题，我不能看到 它基于JavaScript数据一个非常简单的表格设置

如果我删除数据表中的CEL值在columnDefs - 我得到一个错误信息：

数据表警告：表ID = data_id_N3 - 要求为0的行未知参数“0”有关此错误的详细信息，请参阅http://datatables.net/tn/4

如果我添加columnDefs然后由于某些原因，columnDefs - > defaultContent将采用所有默认的con帐篷。

<table width="80%" class="display" id="data_id_N3"></table> 

var dataSet = [{"a":"1","b":"2","c":"3"},{"a":"r","b":"t","c":"y"},{"a":"x","b":"y","c":"z"}]; 


$(document).ready(function() { 
     $('#data_id_N3').DataTable({ 
        data: dataSet, 
        columns: [ 

           { title: "a" } ,  
           { title: "b" } ,  
           { title: "c" } 
        ], 
      columnDefs: [{ 
       targets: '_all',defaultContent: '-' 
       }] 
       });
