element table 自適應(yīng)外面盒子的高度唬滑，可以通過添加自定義指令來解決

1 在src下面創(chuàng)建一個directive文件夾它掂，再創(chuàng)建index.js和tableHeight.js

tableHeight.js 代碼如下：

import {
    addResizeListener,
    removeResizeListener
} from 'element-ui/src/utils/resize-event'

// 設(shè)置表格高度
const doResize = async (el, binding, vnode) => {
    // 獲取表格Dom對象
    const {
        componentInstance: $table
    } = await vnode
    // 獲取調(diào)用傳遞過來的數(shù)據(jù)
    const {
        value
    } = binding
    // if (!$table.height) {
    //   throw new Error(`el-$table must set the height. Such as height='100px'`)
    // }
    // console.log($table, '$table$table$table$table')
    // 獲取距底部距離（用于展示頁碼等信息）
    const bottomOffset = (value && value.bottomOffset) || 30
    if (!$table) return
    // 計算列表高度并設(shè)置
    const height = window.innerHeight - el.getBoundingClientRect().top - bottomOffset
    // $table.layout.setMaxHeight(height)
    $table.layout.setHeight(height)
    // $table.maxHeight = height
    $table.doLayout()
}

export default {
    // 初始化設(shè)置
    bind(el, binding, vnode) {
        // 設(shè)置resize監(jiān)聽方法
        el.resizeListener = async () => {
            await doResize(el, binding, vnode)
        }
        // 綁定監(jiān)聽方法到addResizeListener
        addResizeListener(window.document.body, el.resizeListener)
    },
    // // 綁定默認(rèn)高度
    async inserted(el, binding, vnode) {
        await doResize(el, binding, vnode)
    },
    // // 銷毀時設(shè)置
    unbind(el) {
        // 移除resize監(jiān)聽
        removeResizeListener(el, el.resizeListener)
    }
}

index.js代碼如下：

import tableHeight from './tableHeight'

const install = function (Vue) {
    // 綁定v-adaptive指令
    Vue.directive('tableHeight', tableHeight)
}

if (window.Vue) {
    window['tableHeight'] = tableHeight
    // eslint-disable-next-line no-undef
    Vue.use(install)
}

tableHeight.install = install

export default tableHeight

main.js 里面添加如圖代碼

// 這個是你剛剛寫的index.js的路徑
import tableHeight from '@/directive/index.js'
// 表格自適應(yīng)指令
Vue.use(tableHeight)

模板里面的使用如圖：

     <el-table :data="tableData" stripe style="width: 100%"  height="100px" v-tableHeight="{bottomOffset: 60}">
          <el-table-column prop="date" label="日期" width="180"></el-table-column>
          <el-table-column prop="name" label="姓名" width="180"></el-table-column>
          <el-table-column prop="address" label="地址"></el-table-column>
          <el-table-column prop="caozuo" label="操作"  fixed="right"></el-table-column>
        </el-table>
