vue3.0+ant design vue3.2.6框架的基本使用

1、a-select修改默认样式

通过f12检查元素 发现select选择器和app根节点同级，所以需要添加 getPopupContainer

<a-select ref="select" v-model:value="value1" style="width: 120px" :options="options1" placeholder="请选择" :getPopupContainer="(triggerNode) => triggerNode.parentNode">a-select>

这样你找到它的类名进行修改就可以了
（参考文章：https://blog.csdn.net/weixin_52691965/article/details/124689170?spm=1001.2014.3001.5506）

2、a-modal的使用

①修改默认样式：它也是跟app节点同级 所以要通过getContainer属性改变它的指向(使用这个属性，外面必须包个div)

挂载到对应的div的ref上

参考文章：https://blog.csdn.net/i_am_a_div/article/details/107709190?spm=1001.2014.3001.5506
②关闭刚打开弹窗时的动画，添加transitionName属性即可

transitionName="none" 

3、a-table的使用(固定列、可伸缩列、斑马纹、排序、筛选项)

<a-table class="ant-table-striped" :columns="columns" :data-source="data" size="small" :scroll="{ x: 1500, y: 300 }" :row-selection="rowSelection" :loading="loading" bordered :pagination="false" :row-class-name="(_record, index) => (index % 2 === 1 ? 'table-striped' : null)" @resizeColumn="handleResizeColumn">
            <template #headerCell="{ column, title }">
                <template v-if="column.key === 'name'">
                    <span>{{title}}span>
                template>
            template>
            
            <template #customFilterDropdown="{ setSelectedKeys, selectedKeys, confirm, clearFilters, column }">
                <div style="padding: 8px">
                    
                    <a-date-picker show-time placeholder="查询上传时间"
                        v-if="column.dataIndex == 'uploadTime'" 
                        format="YYYY-MM-DD HH:mm:ss" 
                        :value="selectedKeys[0]"
                        @change="dateString => setSelectedKeys(dateString ? [dateString] : [])" />
                    
                    <a-input
                        v-else
                        ref="searchInput"
                        :placeholder="`查询${column.title}`"
                        :value="selectedKeys[0]"
                        style="width: 188px; margin-bottom: 8px; display: block"
                        @change="e => setSelectedKeys(e.target.value ? [e.target.value] : [])"
                        @pressEnter="handleSearch(selectedKeys, confirm, column.dataIndex)"/>
                    <div style="margin-top:10px;text-align:right;">
                        <a-button size="small" @click="handleReset(clearFilters)" style="margin:0 5px;">重置a-button>
                        <a-button type="primary" size="small" style="margin:0 5px;"
