我正在尝试设置列的宽度,如下所示:

 var per_page = $("table").data("per_page");
  $(".table").dataTable({
    "aoColumnDefs": [
      { "sWidth": "100px", "aTargets": [ 1 ] },
      { "sWidth": "100px", "aTargets": [ 2 ] },
      { "sWidth": "100px", "aTargets": [ 3 ] },
      { "sWidth": "100px", "aTargets": [ 4 ] },
      { "sWidth": "100px", "aTargets": [ 5 ] },
      { "sWidth": "100px", "aTargets": [ 6 ] },
      { "sWidth": "100px", "aTargets": [ 7 ] }
    ],
    "aoColumns" : [
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
    ],
    bJQueryUI: true,
    iDisplayLength: per_page,
    "fnDrawCallback": function( oSettings ) {
      if (oSettings._iDisplayLength == per_page)
        return true
      else {
        $.post($(this).data("url"), {iDisplayLength: oSettings._iDisplayLength})
          .done(function(data){
            if (data.success)
              per_page = oSettings._iDisplayLength;
          });
      }
    }
  })

但结果列宽不是我想要设置的。请问你能帮帮我吗?

更新 1

我已按如下方式更新了我的初始化代码,但在 IE 9 上遇到了奇怪的行为:即采用最长的字段,将其划分为 lines ,并将其长度作为该列所有行的默认值。

  var per_page = $("table").data("per_page");
  $(".table").dataTable({
    sScrollX: "100%",
    aoColumns : [
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
    ],
    bJQueryUI: true,
    iDisplayLength: per_page,
    "fnDrawCallback": function( oSettings ) {
      if (oSettings._iDisplayLength == per_page)
        return true
      else {
        $.post($(this).data("url"), {iDisplayLength: oSettings._iDisplayLength})
          .done(function(data){
            if (data.success)
              per_page = oSettings._iDisplayLength;
          });
      }
    }
  })

更新 2
我更新了如下所示的代码,即 9 中的结果是数据表的标题被调整为新的大小,但表格的其余部分没有被更改,见截图http://gyazo.com/ 282967b051366b18634d4e778205c938 初始化代码:

  var per_page = $("table").data("per_page");
  var datTable = $(".table").dataTable({
    sScrollX: "100%",
    sScrollX: "500px",
    aoColumnDefs: [
          { bSortable: false, aTargets: [ 4, 5,6 ] },
          { sWidth: "16%", aTargets: [  1, 2,3,4,5,6 ] },
    ],
    bJQueryUI: true,
    sAutoWidth: false,
    iDisplayLength: per_page,
    "fnDrawCallback": function( oSettings ) {
      if (oSettings._iDisplayLength == per_page)
        return true
      else {
        $.post($(this).data("url"), {iDisplayLength: oSettings._iDisplayLength})
          .done(function(data){
            if (data.success)
              per_page = oSettings._iDisplayLength;
          });
      }
    }
  })

我该如何解决这种行为?

我在您的Update 2中看到您使用过sAutoWidth,但我认为您输入错误bAutoWidth。尝试改变这一点。

.table如果问题仍然存在,您还可以添加 CSS 规则。

当内容的宽度大于列的标题时,您还应该小心。

所以类似于 1 和 2 的组合:

$('.table').dataTable({
  bAutoWidth: false, 
  aoColumns : [
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '10%' }
  ]
});

您应该使用数据表的“ bAutoWidth”属性并以 % 为每个td /列指定宽度

 $(".table").dataTable({"bAutoWidth": false , 
aoColumns : [
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "10%"},
    ]
});

希望这会有所帮助。

我的做法

$('#table_1').DataTable({
    processing: true,
    serverSide: true,
    ajax: 'customer/data',
    columns: [
        { data: 'id', name: 'id' , width: '50px', class: 'text-right' },
        { data: 'name', name: 'name' width: '50px', class: 'text-right' }
    ]
});

这是我可以让它工作的唯一方法:

JS:

columnDefs: [
            { "width": "100px", "targets": [0] }
        ]

CSS:

#yourTable{
    table-layout: fixed !important;
    word-wrap:break-word;
}

CSS 部分不是很好,但它可以完成工作。

我可以告诉你另一种简单的方法来修复 html 本身中数据表的宽度。

利用

<colgroup>
    <col width="3%">
    <col width="3%">
</colgroup>

这是下面数据表的示例代码:

         <table class="table datatable">
                                <colgroup>
                                    <col width="33%">
                                    <col width="33%">
                                    <col width="33%">
                                    <col width="33%">
                                </colgroup>
                                   <thead>
                                        <tr>
                                            <th>User Id</th>
                                            <th>Name</th>
                                            <th>Email</th>
                                            <th>Phone</th>
                                        </tr>
                                    </thead>
                                        <tr>

                                            <th>delta</th>
                                        </tr>
                                        <tr>
                                            <th>alpha</th>
                                            <th>beta</th>

                                            <th>alpha</th>

我建议不要对 sWidth 使用像素,而是使用百分比。如下所示:

   "aoColumnDefs": [
  { "sWidth": "20%", "aTargets": [ 0 ] }, <- start from zero
  { "sWidth": "5%", "aTargets": [ 1 ] },
  { "sWidth": "10%", "aTargets": [ 2 ] },
  { "sWidth": "5%", "aTargets": [ 3 ] },
  { "sWidth": "40%", "aTargets": [ 4 ] },
  { "sWidth": "5%", "aTargets": [ 5 ] },
  { "sWidth": "15%", "aTargets": [ 6 ] }
],
     aoColumns : [
      { "sWidth": "20%"},
      { "sWidth": "5%"},
      { "sWidth": "10%"},
      { "sWidth": "5%"},
      { "sWidth": "40%"},
      { "sWidth": "5%"},
      { "sWidth": "15%"}
    ]
});

希望能帮助到你。

您可以定义sScrollX : "100%"强制 dataTables 保持列宽:

..
 sScrollX: "100%", //<-- here
 aoColumns : [
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
    ],
...

我在 HTML 标记中设置列宽,如下所示:

    <thead>
        <tr>

            <th style='width: 5%;'>ProjectId</th>
            <th style='width: 15%;'>Title</th>
            <th style='width: 40%;'>Abstract</th>
            <th style='width: 20%;'>Keywords</th>
            <th style='width: 10%;'>PaperName</th>
            <th style='width: 10%;'>PaperURL</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr id="@item.ID">
                <td>@item.ProjectId</td>
                <td>@item.Title</td>
                <td>@item.Abstract</td>
                <td>@item.Keywords</td>
                <td>@item.PaperName</td>
                <td>@item.PaperURL</td>
            </tr>
        }
    </tbody>
</table>

我已经尝试了很多方法。对我有用的唯一方法是:

Yush0 CSS 解决方案:

#yourTable{
    table-layout: fixed !important;
    word-wrap:break-word;
}

与 Roy Jackson HTML 解决方案一起:

    <th style='width: 5%;'>ProjectId</th>
    <th style='width: 15%;'>Title</th>
    <th style='width: 40%;'>Abstract</th>
    <th style='width: 20%;'>Keywords</th>
    <th style='width: 10%;'>PaperName</th>
    <th style='width: 10%;'>PaperURL</th>
</tr>

对于仍然对 1.9.4 更改有问题的人

//oSettings.aoColumns[i].nTh.style.width = _fnStringToCss(oSettings.aoColumns[i].sWidth);
oSettings.aoColumns[i].nTh.style.minWidth = _fnStringToCss(oSettings.aoColumns[i].sWidth);

如果您只需要使用 CSS 设置数据表列的宽度,以下 css 将帮助您:-)

HTML

<table class="table table-striped table-bordered table-hover table-checkable" id="datatable">
    <thead>
    <tr role="row" class="heading">
        <th width="2%">
            <label class="mt-checkbox mt-checkbox-single mt-checkbox-outline">
                <input type="checkbox" class="group-checkable" data-set="#sample_2 .checkboxes" />
                <span></span>
            </label>
        </th>
        <th width=""> Col 1 </th>
        <th width=""> Col 2 </th>
        <th width=""> Col 3 </th>
        <th width=""> Actions </th>
    </tr>
    <tr role="row" class="filter">
        <td> </td>
        <td><input type="text" class="form-control form-filter input-sm" name="col_1"></td>
        <td><input type="text" class="form-control form-filter input-sm" name="col_2"></td>
        <td><input type="text" class="form-control form-filter input-sm" name="col_3"></td>
        <td>
            <div class="margin-bottom-5">
                <button class="btn btn-sm btn-success filter-submit margin-bottom"><i class="fa fa-search"></i> Search</button>
            </div>
            <button class="btn btn-sm btn-default filter-cancel"><i class="fa fa-times"></i> Reset</button>
        </td>
    </tr>
    </thead>
    <tbody> </tbody> 
</table>

使用 metronic 管理主题和我的表 ID 是 #datatable 如上所述。

CSS

#datatable > thead > tr.heading > th:nth-child(2),
#datatable > thead > tr.heading > th:nth-child(3) { width: 120px; min-width: 120px; }
