使用lodop.js打印控件打印table并分页等

import {getlodop} from '@/utils/lodopfuncs.js'
//打印表格
export default{
    // num 打印还是打印预览 condata 对象形式 传入需要的值 自定义 (自己添加的属性要在下面备注)
    // condata  title 标题  orgname科室名字
    lodoptable:function(num,condata){
        //原始table
        var table = document.getelementsbyclassname("tableprin")[0]
        var thead = table.getelementsbytagname("thead")[0]
        var tbody = table.getelementsbytagname("tbody")[0]
        var clnthead = thead.clonenode(true)
        var clntbody = tbody.clonenode(true)
        document.getelementsbyclassname("colnetable")[0].appendchild(clnthead)
        document.getelementsbyclassname("colnetable")[0].appendchild(clntbody)

        var printtable = document.getelementsbyclassname("printtable")[0]
        var printtabletbody = printtable.getelementsbytagname("tbody")[0]

        var tbodychild = printtabletbody.children
        // 循环tbody的子元素
        for (let i = 0; i < tbodychild.length; i++) {
            var tbodytrchild = tbodychild[i].children
            //循环tbody子元素的子元素
            for (let a = 0; a < tbodytrchild.length; a++) {
                // let tbodytrchildspan = tbodytrchild[a].getelementsbytagname("span")
