Question

我需要有关数据表的帮助。我有一个服务器端处理数据表，并且一切正常。该数据表将显示基于使用Ajax的搜索功能的数据。我的问题是，每当我单击搜索按钮将触发搜索功能时，表格标题的高度就会不断增加。谢谢你。

<div class="ibox-content">
                       <div class="table-responsive">
                         <!-- <div class="container" style="margin-top:35px;"> -->
                           <div style="height: 200px;">
                         <table id="search_table" style="width: 100%" cellpadding="0" cellspacing="0" border="0" class="display">
                         <thead>
                           <tr>
                             <th>User ID</th>

我的第一个猜测是，可能是因为您的表中缺少tbody标签。数据表要求table同时具有thead和tbody标签才能正常工作。

您正在HTML本身中指定标题行，尽管我认为这没有任何问题，但也可能是您发出问题的原因。查看下面的代码片段，看看是否可行。

$(function() {
  var data = [{
    u_id: 1,
    u_displayid: 100,
    u_email: "abc",
    ud_first_name: "first",
    u_displayname: "display",
    u_status: "stat",
    ud_dob: "date",
    ud_city: "city",
    ud_phone_number: "phone",
    u_role: "role",
    u_create_date: "create",
    u_modified_date: "modify"
  }];
  $("#search_table").DataTable({
    destroy: true, //elakkan dari error initialise
    language: {
      emptyTable: "Tiada Maklumat Dijumpai!"
    },
    paging: true,
    searching: true,
    deferRender: true,
    data: data,
    order: [
      [11, "desc"]
    ],
    columnDefs: [{
      targets: [0],
      visible: false,
      searchable: false
    }], //hidekan userID
    columns: [{
        title: 'id',
        data: "u_id"
      },
      {
        title: 'display id',
        data: "u_displayid"
      },
      {
        title: 'email',
        data: "u_email"
      },
      {
        title: 'firstname',
        data: "ud_first_name"
      },
      {
        title: 'displayname',
        data: "u_displayname"
      },
      {
        title: 'status',
        data: "u_status"
      },
      {
        title: 'DOB',
        data: "ud_dob"
      },
      {
        title: 'city',
        data: "ud_city"
      },
      {
        title: 'phone',
        data: "ud_phone_number"
      },
      {
        title: 'role',
        data: "u_role"
      },
      {
        title: 'craeted at',
        data: "u_create_date"
      },
      {
        title: 'modified at',
        data: "u_modified_date"
      }
    ]
  });
});

数据表标题的高度不断增加
