基于element-plus UI 框架封装一个table组件

在项目目录下的components新建一个Table.vue

<template>
    <section class="wrap">
        <el-table
            ref="table"
            :data="tableData" 
            v-loading="loading" 
            style="width: 100%"
            :stripe="stripe"
            :border="border"
            :row-key="(row) => { return row.id }"
            @selection-change="handleSelectionChange"
            :height="tableHeight"
            >
            // 复选框列 type="selection"
            <el-table-column
                v-if="selection"
                type="selection"
                width="56"
                align="center"
                :fixed="fixed"
            >
            </el-table-column>
            // 序号列 type="index"
            <el-table-column
                v-if="index"
                type="index"

            ></el-table-column>
            <template v-for="(item, index) in tableProps" :key="index">
                <el-table-column
