datable常规配置,百度一大堆

autoWidth: true,
deferRender: true,
processing: true,
lengthMenu: [10, 25, 50, 100],
colReorder: true,
          stateSave:true,//datatable分页刷新后 固定在当前页
          retrieve:true,//和destroy一起,用于屏蔽Cannot reinitialise DataTable提示的
          destroy:true,
serverSide: false,//true表示服务器端分页,false表示前端分页
pagingType: "full_numbers",
          //有兴趣的话,可以好好研究一下dom,这就很清楚datatable的布局,也好自己加按钮等
//dom: '<"dataTables_header"<"dataTables_toolbar" <"dataTables_controls" r>f>>t<"dataTables_footer row"<"col-md-6 m-t" <"pull-left" l><"pull-left" i>><"col-md-6 m-t"p>><"clearfix">',
