tpl内嵌函数
传入对象到eval_function，再在里面做逻辑处理渲染出来
"tpl": "${{'payLineTicketList': payLineTicketList, isEditStatus: isEditStatus, 'ticketSumAmount': ticketSumAmount }|eval_function:'function transData(params){ const {payLineTicketList = [], ticketSumAmount, isEditStatus} = params; return isEditStatus ? (payLineTicketList || []).reduce((pre,cur) => pre+= Number(cur.remainingAmount || 0),0).toFixed(2) : ticketSumAmount || \'0.00\' }'|number }",
通过表单id和属性取表单值
GETRENDERERDATA("orderCreationDetailForm", "prNum")
