下列的使用js文件。

jquery。数据表。min.js(数据表1.10.16)。
数据表。独自创立min.js(DataTables Bootstrap 3集成)。
数据表。反应敏捷的最小js(响应2.2.1)。
数据表。滚动条。min.js(滚动条1.4.4)。

下列的使用css文件。

jquery。数据表。最小css
数据表。独自创立最小css
反应敏捷的数据表。最小css
滚动条。数据表。最小css

以下是表格布局:

<table class="table table-responsive table-bordered table-striped table-hover" id="tbl-cat-lvl-two" style="width:100%">
    <thead>
        <tr>
            <th>ID</th>
            <th>Code</th>
            <th>Icon</th>
            <th>Category Label</th>
            <th>Precedence</th>
            <th>Visibility</th>
            <th>Actions</th>
        </tr>
    </thead>
    <tbody>
    </tbody>
</table>

以下是表格脚本:

catLvl2table = $('#tbl-cat-lvl-two').DataTable( {
    "processing"    : true,
    "serverSide"    : true,
    "order"         : [[ 4, "asc" ]],
    "responsive"    : true,
    "scrollY"       : "236px",
    "scrollCollapse": true,
    "ajax"          : {
        "url"       : baseUrl+getCatLvl2DataUrl+lvl1CatId,
        "type"      : "POST"
    },
    "columnDefs"    : [
        { "visible"     : false, "targets": [0] },
        { "orderable"   : false, "targets": [0, 2, 5, 6] },
        { 
            className: "align-center check-align-center",
            "targets": [6],
            "render"    : function (data, type, full, meta){
                let id = full.id;
                return `<button href="" class="btn btn-sm btn-info dt-btn-view" data-id="${id}"><i class="fa fa-eye"></i></button><button href="" class="btn btn-sm btn-primary dt-btn-edit" data-id="${id}"><i class="glyphicon glyphicon-pencil"></i></button><button href="" class="btn btn-sm btn-danger dt-btn-del" data-id="${id}"><i class="glyphicon glyphicon-trash"></i></button>`;
            } 
        }
    ],
    "columns": [
        { "data": "id" },
        { "data": "code" },
        { "data": "icon" },
        { "data": "category" },
        { "data": "precedence" },
        { "data": "visibility" },
    ],
});

<table class="table table-responsive table-bordered table-striped table-hover" id="tbl-cat-lvl-two" style="width:100%">
    <thead>
        <tr>
            <!-- <th>ID</th> --> //Remove completely this column
            <th>Code</th>
            <th>Icon</th>
            <th>Category Label</th>
            <th>Precedence</th>
            <th>Visibility</th>
            <th>Actions</th>
        </tr>
    </thead>
    <tbody>
    </tbody>
</table>

只需从“columnDefs”数组中删除以下代码。

{ 
    className: "align-center check-align-center",
    "targets": [6],
    "render"    : function (data, type, full, meta){
        let id = full.id;
        return `<button href="" class="btn btn-sm btn-info dt-btn-view" data-id="${id}"><i class="fa fa-eye"></i></button><button href="" class="btn btn-sm btn-primary dt-btn-edit" data-id="${id}"><i class="glyphicon glyphicon-pencil"></i></button><button href="" class="btn btn-sm btn-danger dt-btn-del" data-id="${id}"><i class="glyphicon glyphicon-trash"></i></button>`;
    } 
}

并添加此代码:

"columns": [
        { "data": "code" },
        { "data": "icon" },
        { "data": "category" },
        { "data": "precedence" },
        { "data": "visibility" },
        { "data" : null,
            className : "align-center" // You should style for this class
        }
],
"rowCallback": function(row, data, index) {
    $('td:eq(5)', row).html(
        '<button href="" class="btn btn-sm btn-info dt-btn-view" data-id="'+data.id+'"><i class="fa fa-eye"></i></button>'+
        '<button href="" class="btn btn-sm btn-primary dt-btn-edit" data-id="'+data.id+'"><i class="glyphicon glyphicon-pencil"></i></button>'+
        '<button href="" class="btn btn-sm btn-danger dt-btn-del" data-id="'+data.id+'"><i class="glyphicon glyphicon-trash"></i></button>'
    );
},

在外部css类中

.align-center {
  text-align: center; // whatever you want
}
