el-pagination 响应式布局该如何实现？具体代码

el-pagination 响应式布局可以通过设置不同屏幕尺寸下的显示数量来实现。具体代码如下：

<el-pagination
  :total="total"
  :page-size="pageSize"
  :current-page="currentPage"
  :layout="layout"
  @current-change="handleCurrentChange"
/>

<script>
export default {
  data() {
    return {
      total: 100,
      pageSize: 10,
      currentPage: 1,
      layout: ['prev', 'pager', 'next', 'sizes', 'total', 'slot']
    }
  },
  methods: {
    handleCurrentChange(val) {
      this.currentPage = val
    }
  },
  mounted() {
    if (window.innerWidth < 768) {
      this.layout = ['prev', 'pager', 'next', 'total']
      this.pageSize = 5
    } else if (window.innerWidth < 992) {
      this.layout = ['prev', 'pager', 'next', 'sizes', 'total']
      this.pageSize = 10
    } else {
      this.layout = ['prev', 'pager', 'next', 'sizes', 'total', 'slot']
      this.pageSize = 20
    }
    window.addEventListener('resize', () => {
      if (window.innerWidth < 768) {
        this.layout = ['prev', 'pager', 'next', 'total']
        this.pageSize = 5
      } else if (window.innerWidth < 992) {
        this.layout = ['prev', 'pager', 'next', 'sizes', 'total']
        this.pageSize = 10
      } else {
        this.layout = ['prev', 'pager', 'next', 'sizes', 'total', 'slot']
        this.pageSize = 20
      }
    })
  }
}
</script>

上述代码中，通过设置不同尺寸下的 `layout` 和 `pageSize`，实现了 el-pagination 响应式布局。在 `mounted()` 钩子函数中，通过监听窗口大小变化，不断更新 `layout` 和 `pageSize`。这样，当屏幕尺寸发生变化时，el-pagination 会动态地调整布局和显示数量。
