NUI中gird合并展开无法正常显示问题解决方案

nui.DataGrid.prototype.expand=function(){
this.expanded=true;
if(this._height)

this.el.style.height=this._height;

this._viewportEl.style.display="block";
if(this.state!="max")

delete this._height;

mini.removeClass(this.el,"mini-panel-collapse");
this.doLayout();
}; 重写
重写GIRD的EXPAND方法，如下：

nui.DataGrid.prototype.expand=function(){

this.expanded=true;

if(this._height)

this.el.style.height=this._height;

this._viewportEl.style.display="block";

if(this.state!="max")

delete this._height;

mini.removeClass(this.el,"mini-panel-collapse");

this.doLayout();

};
