jQuery dataTable不显示排序图标

$('#example').dataTable(
{
    "bPaginate": false,"bFilter": false,"oLanguage": { "sInfo": ""}        
}
);

<table class="surfClass" cellspacing="1" id="example">

<thead>
<tr>
    <th width="120px">Name</th>
    <th width="120px">The hourly rate (points)</th>
    <th>Levels of referrals</th>
    <th>bonuses</th>
    <th width="70px">Payout minimum</th>
</tr>
</thead>

我有这个问题,我发现因为我已经将CDN脚本复制到我的本地机器,它没有正确地引用图像,正如@ Matt2012指出的.所以我的解决方案是更新CSS文件,以寻找那些我想要放置它们的图像,在我也保存它们之后.

看这部分：

table.dataTable thead .sorTing { BACkground: url('/Content/images/sorT_Both.png') no-repeat center right; }
table.dataTable thead .sorTing_asc { BACkground: url('/Content/images/sort_asc.png') no-repeat center right; }
table.dataTable thead .sorTing_desc { BACkground: url('/Content/images/sort_desc.png') no-repeat center right; }

table.dataTable thead .sorTing_asc_disabled { BACkground: url('/Content/images/sort_asc_disabled.png') no-repeat center right; }
table.dataTable thead .sorTing_desc_disabled { BACkground: url('/Content/images/sort_desc_disabled.png') no-repeat center right; }
