easyui datagrid footer的问题

[哎呀好气啊]

easyui datagrid footer 怎么配置？

这是我后台穿过来的JSON数据

{"total":1,"footer":[{"name":"总计","sum":1}],"rows":[{"trainId":"1038","trainType":"特快","arrivalTime":1516249320000,"mile":500,"num":1,"runtime":16.0,"startStation":"杭州","startTime":1516191720000,"trainNo":"K819","arrivalStation":"上海"}]}

前台怎么配置columns才能正常显示footer，我已经设置了showFooter:true.

easyui 版本 1.5.4

[Hello World,]

footer的列名要和rows的一致
