如何向jQuery dataTables列中添加一些信息

Question

我有此代码：

 $("table.contentTable").dataTable({
        "iDisplayLength": 25,
        "oLanguage": {
            "sUrl": "scripts/language/ru_RU.txt"
        },
        "aaSorting": sorting,
        /* "bJQueryUI": true,*/
        "bRetrieve": true,
        "bProcessing": true,
        "bServerSide": true,
        "sPaginationType": "paging_with_jqui_icons",
        "sAjaxSource": "getAllTripCards",
        "fnServerData": fnDataTablesPipeline,
        "aoColumns": [
            {"mDataProp": "cardNumber"},
            {"mDataProp": "issueDate", "sType": "string-date-euro"},
            {"mDataProp": "type"},
            {"mDataProp": "position"}

...

我需要在第一栏中添加两个字段的组合。我怎样才能做到这一点？我想做这个，但是不起作用

 "aoColumns": [
            {"mDataProp": "cardNumber" + "issueDate"},

Answer 1

您可以尝试这个：

$(table.column(1).header()).text('cardNumber/year');

参考链接：

column().header() API

Answer 2

"aoColumns": [
        {"mDataProp": "cardNumber"},
        { "mDataProp": function (data, type, dataToSet) {
        return data.issueDate + " " + data.sType;}},
        {"mDataProp": "type"},
        {"mDataProp": "position"}

]，
