[b]Javascript处理[/b]
通常在表格的"load"数据加载完成事件中，更新表格的汇总信息：
grid.on("load", onGridLoad);

function onGridLoad(e) {
var result = e.result;
var grid = e.sender;

var cellEl = grid.getSummaryCellEl("ageColumn");
cellEl.style.cssText = "text-align:right";
cellEl.innerHTML = ""
+ 'Min=' + result.minAge + "
"
+ 'Max=' + result.maxAge + "
"
+ 'Avg=' + result.avgAge + "
"
+ "";

var cellEl = grid.getSummaryCellEl("totalColumn");
cellEl.innerHTML = "总员工数：" + result.total;
}

[b]服务端数据处理[/b]
在服务端返回表格分页数据时，我们额外增加了一些属性，比如minAge、maxAge、avgAge等，代码如下：
public Hashtable SearchEmployees(string key, int index, int size, string sortField, string sortOrder)
{
ArrayList employees = ......; //分页后的数据
int totalCount = ......; //总记录数

Hashtable result = new Hashtable();
result["data"] = employees;
result["total"] = totalCount;

//生成一些汇总信息
ArrayList ages = DBUtil.Select("select min(age) as minAge, max(age) as maxAge, avg(age) as avgAge from t_employee");
Hashtable ageInfo = ages[0] as Hashtable;
result["minAge"] = ageInfo["minAge"];
result["maxAge"] = ageInfo["maxAge"];
result["avgAge"] = ageInfo["avgAge"];

return result;
}
