我有像这样的数据表
<table id="tbl-cfrmvsreal" class="dataTable table table-bordered table-hover table-full-width" width="100%" data-table="tablekk" data-detail="dthkksub">
<thead>

这是我的jquery
var table = $("#tbl-cfrmvsreal");
var target = table.attr('data-table');
//console.logconsole.log(host+'konrtakkerja/'+target);
var oTable = table.on( 'processing.dt', function ( e, settings, processing ) {
if (processing) {
$(this).find('tbody').addClass('load1 csspinner');
} else{
$(this).find('tbody').removeClass('load1 csspinner');
};
} ).DataTable({
"bServerSide": true,
"ajax": host+'datatable/'+target,
"columnDefs": [{
"targets": [ -1 ],
"className": "dt-body-left",
},
{
"targets": [ 2 ],
"className": "details-control",
}],
//add by tiar 5 mei 2017
"aoColumns": [null,null,null
,null,null,null
,null,{"sClass": "alignRight"},null
,null,{"sClass": "alignRight"}],
//end
"footerCallback": function ( row, data, start, end, display ) {
// I don't know how to put these code for footer
}
});
但是我的问题是，它显示错误Uncaught TypeError: Cannot set property 'nTf' of undefined，我知道错误的含义，但是我也需要排第二行。
我想在页脚上显示2行，第一行用于汇总货币USD，第二行用于汇总货币IDR。但是我不知道该怎么做。这些有什么解决办法吗？
编辑：没关系，我找到了另一种解决方案。那么页脚并不是最佳选择。我只是将摘要分为另一个数据表。因此，谢谢您帮助我的问题。
