Datatables 在jQuery数据表中指定固定列宽

我试图为jQuery数据表中的几列指定固定宽度。我试图通过中指定的列定义来实现这一点，但列和列标题仍然会自动调整大小

以下是我一直在使用的JSFIDLE：

JavaScript:

var table = $('#example2').DataTable({
        "tabIndex": 8,
        "dom": '<"fcstTableWrapper"t>lp',
        "bFilter": false,
        "bAutoWidth": false,
        "data": [],
        "columnDefs": [
            {
                "class": 'details-control',
                "orderable": false,
                "data": null,
                "defaultContent": '',
                "targets": 0
            },
            { 
                "targets": 1},
            { 
                "targets": 2,
                "width": "60px"},
            { 
                "targets": 3,
                "width": "1100px"},
            { 
                "targets": 4},
            { 
                "targets": "dlySlsFcstDay"},
            { 
                "targets": "dlySlsFcstWkTtl",
                "width": "60px"}
        ],
        "order": [
            [1, 'asc']
        ]
    });

当我检查实时代码时，我可以看到我在列定义中指定的宽度作为样式属性添加到列中，但它与列的实际宽度不匹配。

这不是DataTables的问题。看见基于此算法，我看到以下两种解决方案

解决方案1

自己计算桌子的宽度，并进行相应的设置

#example {
  width: 3562px;
}

请参见此处的实时示例：

解决方案2

设置每个单元格的最小内容宽度（MCW），并让用户代理确定列宽

为此，请将类添加到目标列，以便能够设置它们的样式：

var table = $('#example').DataTable({
  tabIndex: 8,
  dom: '<"fcstTableWrapper"t>lp',
  bFilter: false,
  bAutoWidth: false,
  data: [],
  columnDefs: [{
    class: 'details-control',
    orderable: false,
    data: null,
    defaultContent: '',
    targets: 0
  }, {
    targets: 1
  }, {
    class: 'col-2',
    targets: 2
  }, {
    class: 'col-3',
    targets: 3
  }, {
    targets: 4
  }, {
    targets: 'dlySlsFcstDay'
  }, {
    targets: 'dlySlsFcstWkTtl'
  }],
  order: [[1, 'asc']]
});

请参见此处的实时示例：。

：

设置自动宽度：false

将px值设置为前3列

重要提示：检查表格宽度是否大于3列+最后一列

调整表格宽度和第四列

$('#example').DataTable({ //four column table
   autoWidth: false, //step 1
   columnDefs: [
      { width: '300px', targets: 0 }, //step 2, column 1 out of 4
      { width: '300px', targets: 1 }, //step 2, column 2 out of 4
      { width: '300px', targets: 2 }  //step 2, column 3 out of 4
   ]
});

设置工作台宽度，4*300px：

     #example { width: 1200px };

因此，您将看到前3列的宽度为300px，最后一列的宽度为150px（需要额外调整）

---

最后但并非最不重要的一点：当单元格包含过长（>300px，无空格）字时，固定列大小300px不会阻止您。因此，您必须记住，所有单词必须小于列的固定边。

对于

标记或其

css类或css id，请添加以下样式：

`table{
     margin: 0 auto;
     width: 100%;
     clear: both;
     border-collapse: collapse;
     table-layout: fixed;
     word-wrap:break-word;
}`

设置固定列宽可能是一件非常痛苦的事情。下面的解决方案工作得很好


{宽度：250，目标：1，类：“someClass”，
呈现：函数（数据、类型、行）{
如果（类型==‘显示’）{
返回`${data}`；
}
返回数据；
}
}
$（“#示例”）.DataTable（{autoWidth:false，//首先关闭autoWidth，然后
