如何使用Element實(shí)現(xiàn)表格表頭添加搜索圖標(biāo)和功能

今天小編給大家分享一下如何使用Element實(shí)現(xiàn)表格表頭添加搜索圖標(biāo)和功能的相關(guān)知識點(diǎn)，內(nèi)容詳細(xì)，邏輯清晰，相信大部分人都還太了解這方面的知識，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。

Element 表格表頭添加搜索圖標(biāo)和功能

主要實(shí)現(xiàn) table的slot=‘header’

• headerData是表頭的循環(huán)數(shù)組

• tableData是表格內(nèi)容的數(shù)組

• <template slot="header"></template> 自定義表頭的內(nèi)容

• 注意：在使用<template slot="header"></template>的時(shí)候，只會顯示表頭的自定義內(nèi)容，表格的內(nèi)容還需要使用<template slot-scope="scope"> {{ scope.row }} </template> scope.row會顯示出該列的所有內(nèi)容

• 如果<template slot='header'></template>不使用slot-scope='scope'會出現(xiàn)不能輸入的問題

• Vue 2.6+版本的插槽語法使用#header替換<template slot='header' slot-scope='scope'></template>Vue的作用域插槽

<template>
    <el-table :data="tableData" >
        <template v-for="(headerItem, headerIndex) in headerData">
            <!-- 下拉框選擇器 -->
            <el-table-column
                v-if="headerItem.select"
                :label="headerItem.label"
