请教一个 vue3 自定义组件传 h 函数问题

我是用 naiveUI 的 datatable 时自己写一个过滤菜单样式,我目前可以按照预期运行,传入 title 还有 value 还有图标的 src 链接. 格式

[{title:'标签名', value:'test', imgSrc='1.jpg'}] 

现在我要允许传递一个 h 函数进去,像这样

[{title:'标签名', value:'test', imgSrc:'1.jpg', icon:h('div',null,'我是图标')}] 

但是我不知道这个子组件接收到之后怎么把这个 icon 函数放进去 li 标签里面,直接在 h 函数里把 NList 标签用 h 函数来写,像下面的方法,但是他会报错,浏览器全都是下面的报错,我想问下这个要怎么处理才比较好一点
