datatable-固定行固定列

之前用fixed-table.js 写了一个固定行，固定列的效果，缺点是 无法随着屏幕自适应宽度，所以被产品pass掉了，还是继续看datatable的坑。

datatable这个是一个很强大的表格工具，之前只有英文文档，用于系统管理平台的开发有很大的用处，现在出了中文文档，更方便了。

现在记录一下实现步骤，方便以后继续研究。

实现的效果图，原理应该都是一样的 三个表格，实现固定行，固定列，不过datatable 是一套配置，自动生成的。

css:

    <link rel="stylesheet" type="text/css" href="assets/global/plugins/datatables/extensions/Scroller/css/dataTables.scroller.min.css" />
    <link rel="stylesheet" type="text/css" href="assets/global/plugins/datatables/extensions/ColReorder/css/dataTables.colReorder.min.css" />
    <link rel="stylesheet" type="text/css" href="assets/global/plugins/datatables/plugins/bootstrap/dataTables.bootstrap.css" />

 js:

<script type="text/javascript" src="assets/global/plugins/datatables/media/js/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="assets/global/plugins/datatables/extensions/Scroller/js/dataTables.scroller.min.js"></script>

<script type="text/javascript" src="assets/global/plugins/datatables/extensions/FixedColumns/js/dataTables.fixedColumns.min.js"></script>

实现：

html:

js

   $('#sample_6').DataTable({
            //文案展示
            "language": {
                "sProcessing": "处理中...",

                { "data": "no", className: "text-center" },
                {"data": "Guestguid", className: "text-center"},
                { "data": "Type", className: "text-center", },

                    "data": "Institution",
                    "render": function (data, type, full, meta) {
                     
                        return '<input type="checkbox"  class="tablesingle" lay-ignore name="tablesingle"  value="" />'

                    },
                    "bSortable": false
                },
                {
                    "sClass": "text-center",
                    "data": "Contacttel",
                    "render": function (data, type, full, meta) {

                        return '<input type="checkbox"  class="tabledouble" lay-ignore name="tabledouble"  value="" />'

                    },
                    "bSortable": false
                },
            ],
        });

json数据形式

这样就生成一个 不带分页的 自适应，固定列的表格了
