首先为表格添加showFooter: true属性
然后为列添加footerFormatter属性

var templateTableParams = {
        classes: "table table-bordered table-hover",
        url: "后台访问路经",

        striped: true,    //是否显示行间隔色
        singleSelect: true,   //单选
        clickToSelect: true,  //是否启用点击选中行
        showFooter:true,//合计
        height:trueHeight,
        queryParams:function () {
