在colModel中使用新的事件cellattr，我们可以轻松的配置数据跨度。
需要注意的是我们通过单元格属性，我们可以将任何有效的属性设置到单元格上，包括样式。
HTML代码举例
<html>
<head>
<title>jqGrid 实例</title>
</head>
<body>
···代码省略···
<table id="colspan"></table>
<div id="pcolspan"></div>
···代码省略···
</body>
</html>
javascript代码举例
$(function(){
pageInit();
});
function pageInit(){
jQuery("#colspan").jqGrid({
url:ctx+'/JSONNameData',
datatype: "json",
colNames:['Date', 'Inv No', 'Client', 'Amount','Tax','Total','Notes'],
colModel:[
{name:'invdate',index:'invdate', width:90},
{
name:'id',
key : true,
index:'id',
width:55,
cellattr: function(rowId, value, rowObject, colModel, arrData) {
return ' colspan=2';
},
formatter : function(value, options, rData){
return "Invoce: "+value + " - "+rData['name'];
}
},
{name:'name', index:'name', width:100,
cellattr: function(rowId, value, rowObject, colModel, arrData) {
return " style=display:none; ";
}
},
{name:'amount',index:'amount', width:80, align:"right"},
{name:'tax',index:'tax', width:80, align:"right"},
{name:'total',index:'total', width:80,align:"right"},
{name:'note',index:'note', width:150, sortable:false}
],
rowNum:10,
width:700,
rowList:[10,20,30],
pager: '#pcolspan',
sortname: 'invdate',
viewrecords: true,
sortorder: "desc",
jsonReader: {
repeatitems : false
},
caption: "Data colspan",
height: '100%'
});
jQuery("#colspan").jqGrid('navGrid','#pcolspan',{edit:false,add:false,del:false});
}
