看效果图是否是你需要的

这是原来没有Element-ui框架的

 首先，你要在你的项目里安装Element-ui
yarn命令

 yarn add element-ui

npm命令

npm install element-ui --save

 好了现在可以粘贴代码

Vue.use(Vuex)

            state.goodsList.push({ id: state.goodsList.length + 1, name, price })
        },
        delGood(state, id) {
            const index = state.goodsList.findIndex(item => item.id === id)
            if (index !== -1) {
                state.goodsList.splice(index, 1)
            }
        },
        updateGood(state, { id, name, price }) {
