数据表 - 设置列宽

标签: javascript datatables jquery-datatables

我正在尝试设置列宽,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;
          });
      }
    }
  })

但是产生的列宽并不是我想要设置的。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,获取最长的字段,将其分成行,并将其长度作为此列的所有行的默认值。

  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
我已经更新了如下所示的代码,ie 9中的结果是数据表的标题被调整为新大小,但表的其余部分未被更改所取代,请参见屏幕截图http://gyazo.com/282967b051366b18634d4e778205c938 初始代码:

  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;
          });
      }
    }
  })

如何解决此问题?

我在您的 Update 2 中看到您使用了sAutoWidth,但我认为您错误输入了bAutoWidth。试着改变这个。

如果问题仍然存在,您还可以向.table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1的组合。 2:

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

你应该使用  数据表的“bAutoWidth”属性,并为%

中的每个td /列提供宽度
 $(".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。

答案 3 :(得分:2)

我建议不要使用像素作为sWidth,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%"}
    ]
});

希望它有所帮助。

您可以定义sScrollX : "100%"以强制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"},
    ],
...

这是我能让它发挥作用的唯一方法:

JS:

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

CSS:

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

CSS部分不是很好但是它能完成这项任务。

我在HTML标记中设置列宽如下:

                                                     

    <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>

如果您只需要使用CSS设置数据表列的宽度,则遵循CSS可以帮助您:-)

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管理员主题,并且我的表ID是上面的#datatable。

CSS

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

我可以告诉您另一种简单的方法来修复html本身中数据表的宽度。

使用

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

下面是数据表的示例代码:

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

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