在data中引入静态图片路径

首先tempate中内容都一样：

      <template slot="pic" slot-scope="{ row }">
        <img :src="row.pic" alt="" height="100px" width="100px">
      </template>

图片如果直接写在template中：

<img src="../../../../assets/images/mapicon.png" alt="查看"/>

data中直接引入图片的静态地址：

        {
          id: '2',
          name: '王冬冬',
          pic: '../assert/images/4.jpg',
          price: '43.65',
          checked: true,
          count: 2
        },

很奇怪的是，在我这里引入这个不管用，识别不了路径，具体什么原因不清楚，但是我看到很多博主都有阐述，所以这里记录一下。

import直接导入：

首先将图片放在assets文件夹下，然后引用：

import smile from '../assets/images/3.jpg'

data中：

        {
          id: '0',
          name: '王小明',
          pic: smile,
          price: '43.65',
          checked: false,
          count: 0
        },

require导入：

          pic: require('../assets/images/5.jpg'),

attrs：

        {
          title: '图片',
          key: 'pic',
          render: (h, params) => {
            return h('img', {
              attrs: {
                src: params.row.pic
              },
              style: {
                height: '100px',
                width: '100px'
              }
            })
          },
          slot: 'pic'
        },

附上源码：

<template>
  <div class="container">
    <h1>LOL英雄皮肤购物车</h1>
    <router-link to="/about">About</router-link>
    <Table :columns="columns1" :data="data1">
      <template v-slot="{row}">
        <Checkbox v-model="row.checked">Checkbox</Checkbox>
      </template>
      <template slot="pic" slot-scope="{ row }">
        <img :src="row.pic" alt="" height="100px" width="100px">
      </template>
      <template slot="total" slot-scope="{ row }">
        <span>{{ conputedTotal(row.price, row.count) }}</span>
      </template>
      <template slot="action" slot-scope="{ row, index }">
        <Button type="error" @click="remove(index)">删除</Button>
      </template>
    </Table>
    <div class="footer">
      <h1>总计：{{ total }}</h1>
      <p>
        <Button type="success" @click="submit(index) ">微信支付</Button>
      </p>
    </div>
  </div>
</template>

成品截图：

办法很多，但是sttrs和props的区别，我看不出来，

下面的这段代码搞不懂：

{
  title: '头像', key: 'headimg',
  render: (h, params) => {
    console.log(params.row)
    return h('div', {
      attrs: {
        style: 'width: 40px;height: 40px;'
      },
    }, [
        h('img', {
          props: {
            type: 'primary',
            size: 'small'
          },
          attrs: {
            src: params.row.headimg, style: 'width: 40px;height: 40px;border-radius: 2px;'
          },
          style: {
          },
        }),
      ]);
  }
},

props和attrs，都用到了，这里有介绍博客，但是没太读懂：
