如何在jQuery DataTables中动态添加<tfoot>？

这里是我的代码： -如何在jQuery DataTables中动态添加<tfoot>？

function get_dataset(data){ 
    columns_1 = [{}]; 
    dataset = []; 
    keys = Object.keys(data); 
    arr = Object.keys(data[keys[0]]); 
    for (i = 0; i < arr.length; i++) { 
     columns_1.push({ 
      'title': arr[i], 
     }); 
    } 
    for (i = 0; i < keys.length; i++) { 
     local_arr = []; 
     local_arr.push(keys[i]); 
     for (j = 0; j < arr.length; j++) { 
      local_arr.push(data[keys[i]][arr[j]]); 
     } 
     dataset.push(local_arr); 
    } 
    return dataset 
} 

function handleReportSuccess(data) { 
    var dataset = get_dataset(data); 
    datatable = $('#restaurant_number_table').DataTable({ 
     data: dataset, 
     columns: columns_1 
    }); 
    $('.reviews-cont').show(); 
}

这是当前结果： enter image description here

我想要的结果是有 “THEAD” 列： “活动”， “删除”， “编辑” ，“不活跃”，“tfoot”中的“temporary_inactive”，你能帮我做到这一点吗？

你可以像下面： -

$("#datatable-id").append(
    $('<tfoot/>').append($("#datatabale-id thead tr").clone()) 
);

例子： -

$(document).ready(function() { 
 
    $('#example').DataTable(); 
 
    $("#example").append(
 
     $('<tfoot/>').append($("#example thead tr").clone()) 
 
    ); 
 
});
