pageLength in Datatable

Question

我試圖設置Datatable的pageLength爲6，但它不顯示6在計數。見附圖

$('#tblProviders').dataTable({ 
    "autoWidth": false, 
    "searching": false, 
    "pageLength": 6, 
    "bDestroy": true, 
    data: data, 
    columns: [ 
       { "data": "ProviderName" }, 
       { "data": "ProviderQualificationTime" }, 
       { "data": "TotalServiceableOffers" } 
    ] 
}); 

Answer 1

在你的代碼添加lengthMenu

"lengthMenu": [ 
     [6,10, 20, 50, 100, 150, -1], 
     [6,10, 20, 50, 100, 150, "All"] // change per page values here 
],
