datatable 序号和使用
注意这段代码：
{"data" : 'KeyId',
"render" : function(data, type, full, meta){
if(meta.settings && meta.settings.aLastSort){
if(meta.settings.aaSorting[0][1] == 'asc'){
return meta.row + 1 + meta.settings._iDisplayStart;
}else if(meta.settings.aaSorting[0][1] == 'desc'){
//倒序
return (meta.settings.aiDisplay.length-meta.row) + meta.settings._iDisplayStart;
}
}
}},
//禁止alert显示警告和错误
var _wh__Table___;
initData();
$.fn.dataTable.ext.errMode = 'none'; //不显示任何错误信息
function initData(){
//datatables
_wh__Table___ = $("#tab_orderList").dataTable({
