webix .datatable 表格分页

grid表格返回参数大都是以下这种格式（参数名可能不一样）

{
 
data:[{...},{...} ...],
count:39
 
 }

webix的参数格式为

{
data：[{...},{...},{...}, ...],
pos:8,                //从第几行开始接下去，相当于【（page-1）*size】）
total_count:35  //总共有多少条
}

webix 分页我目前测出来的情况是返回 total_count 的值是多少，初始化的时候回一次查完出来，于是我返回的时候只返回 Math.min(page*size +1,count) +1的原因是为了显示下一页

效果如下

datatable的代码

define(function() {

    return {
