Antd+vue Input下拉Table表格

遇到需要下拉选择信息的需求，发现Select 展示信息不太友好，尝试Input标签触发展示一个Table表格

AInputTable 组件 使用文档

• 说明: 输入框支持展示Table表格,支持翻页,多属性展示,
• 点击选中可获取列全部属性值;

参数配置

使用示例

<template>
    <a-input-table :="tableAIdConfig" v-model="queryParam.tableAId" @getRecord="getRecord"></a-input-table>
</template>
<script>
    import AInputTable from "@/components/assien/AInputTable";
    export default {
        name: "Test",
        components: {
          AInputTable,
        },
        data() {
            return {
                queryParam: {},
                tableAIdConfig: [{
		          title: '序号',
		          width: 60,
		          align: "center",
		          dataIndex: 'no',
		          customRender: function (t, r, index) {
		            return parseInt(index) + 1
		          },
		        },{
