项目中由于需要用到合并单元格、拆分等功能，用普通的table虽然可以满足要求，但是样式很难看，而且控制起来非常吃力，这几天在专门搞这个东西玩。

对于表头的数据，具体的部分数据由后台产生抛出，表示每个月的具体工作日工作周。

 	var columns = [		
   			{name:"bigTitle",caption:reportData.bigTitle,children:[
				{name:"orgName",caption:"组织结构名称",width:100,mode:"string"},                                                   
				{name:"helpinfo",caption:reportData.columnCaption[0],
					children:[{name:"workday_month",caption:"工作日数",width:80,mode:"number",format:"#"},
				     	     {name:"loggedday_month",caption:"登录天数",width:80,mode:"number",format:"#"}]
				},
				{name:"helpinfo",caption:reportData.columnCaption[1],
					children:[{name:"workday_week1",caption:"工作日数",width:70,mode:"number",format:"#"},
					          {name:"loggedday_week1",caption:"登录天数",width:70,mode:"number",format:"#"}]
				},
				{name:"helpinfo",caption:reportData.columnCaption[2],
					children:[{name:"workday_week2",caption:"工作日数",width:70,mode:"number",format:"#"},
					          {name:"loggedday_week2",caption:"登录天数",width:70,mode:"number",format:"#"}]
				},	
				{name:"helpinfo",caption:reportData.columnCaption[3],
					children:[{name:"workday_week3",caption:"工作日数",width:70,mode:"number",format:"#"},
					          {name:"loggedday_week3",caption:"登录天数",width:70,mode:"number",format:"#"}]
				},	
				{name:"helpinfo",caption:reportData.columnCaption[4],
					children:[{name:"workday_week4",caption:"工作日数",width:70,mode:"number",format:"#"},
					          {name:"loggedday_week4",caption:"登录天数",width:70,mode:"number",format:"#"}]
				},	
				{name:"helpinfo",caption:reportData.columnCaption[5],
					children:[{name:"workday_week5",caption:"工作日数",width:70,mode:"number",format:"#"},
					          {name:"loggedday_week5",caption:"登录天数",width:70,mode:"number",format:"#"}]
				}
   			]}			
   		];

这个用于控制删除没有数据的表头

   	for(n=5;n>=0;n--){
   		if(reportData.columnCaption[n]==null)
   			columns[0]['children'].pop();
   	}

这个小组件还是非常好用的，支持json格式，支持ajax调用，支持一些简单的运算，支持jquery。
