Element 表格表頭添加搜索圖標和功能

主要實現 table的slot=‘header’

• headerData是表頭的循環數組

• tableData是表格內容的數組

• <template slot="header"></template> 自定義表頭的內容

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

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

• 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"
                :prop="headerItem.prop"
                :key="headerIndex"
            >
            	<!-- 表頭的 slot -->
                <template #header>
                    <el-popover placement="bottom" title="請選擇" width="200" trigger="click">
                        <div slot="reference" class="search-header">
                            <span class="search-title">{{ headerItem.label }}</span>
                            <i class="search-icon el-icon-search"></i>
                        </div>
                        <el-select v-model="headerItem.selectValue" placeholder="請選擇">
                            <el-option
                                v-for="item in headerItem.selectOptions"
                                :key="item.value"
                                :label="item.label"
                                :value="item.value"
                            >
                            </el-option>
                        </el-select>
                    </el-popover>
                </template>
                <!-- 表格的 內容 slot -->
                <template slot-scope="scope">
                    {{ scope.row[headerItem.prop] }}
                </template>
            </el-table-column>
            <!-- 日期選擇器 -->
            <el-table-column

                <template #header>

                <template slot-scope="scope">
                    {{ scope.row[headerItem.prop] }}
