el-table实现单选及点击当前行选中

<base-table v-loading="table.loading" :data="table.data" :empty-text="table.empty"
                    @current-change="handleSelectionChange">
            <el-table-column width="55" >
                <template #default="{row}">
                    <el-radio v-model="currentRow" :label="row">&nbsp;</el-radio>
                </template>
            </el-table-column>
            <el-table-column label="序号"  type="index" width="55" />
            <el-table-column label="事项编码"  prop="matterCode"  show-overflow-tooltip/>
            <el-table-column label="事项名称"  prop="matterName"  show-overflow-tooltip/>
            <template #noOperate></template>
        </base-table>

// 单选框的绑定值要定义一个空对象

const multipleSelection = ref([]);

const currentRow = ref({});

const handleSelectionChange = (val) => {
    multipleSelection.value = [val]; // 获取当前选中的值
    currentRow.value = val; // 点击行,让对应的单选选中的值和表格的选中值保持一致
}
