1、需要指定datatables的ID

1 <button class="btn  btn-primary" id="newAttribute">新增证照属性</button>
2 <table class="table table-striped table-bordered table-hover dataTable myTable" id="newAttributeTable" width="100%" role="grid"   aria-describedby="editable_info">
3 </table>

2、初始化datatables

<script type="text/javascript">
$(function() {
//初始化证照属性设置表
initnewAttributeTable();
});

//证照属性设置表

function initnewAttributeTable() {
var table = $('#newAttributeTable').dataTable({
"paging": false, //翻页
    //"bPaginate" : true,      //显示分页器
    //"iDisplayLength":28,
"ordering": false,
"searching": false, //搜索框
    //"bLengthChange":true,//改变每行显示数据数量
    //"aLengthMenu": [[10, 30, 50, -1], [10, 30, 50, "All"]],

$(nTd).html(iRow + 1 + startnum); //分页行号累加：$(nTd).html(iRow+1);
}
    }, {
"data": "typeName",
"title": "证照属性设置"

"data": null,

"columnDefs": [
      {

}
      }
    }, {

//新增一行表格
$("#newAttribute").unbind('click').click(function () {
