Layui Table模块 Field 添加path取值

目前Layui的Table模块想要使用path来取值的话 只能使用template，有些麻烦，

我们通过源码的修改，让field也支持path取值

代码位于 table.js 220行左右 方便大家使用给出文字版

 if(typeof c === 'string' && c.split('.').length > 1){
                            const keyPaths = c.split('.')
                            let tmp  = l
                            for (let j = 0;j < keyPaths.length ;j ++){
                                tmp = tmp\[keyPaths\[j\]\]
                                if(!tmp){
                                    if(r.templet){
                                        tmp = r.templet\[l\]
                                    }else{
                                        tmp = r.defaultValue || ''
                                    }
                                    break
                                }
                            }
                            p = tmp
                            l\[c\] = tmp
                        }
