错误代码

<el-pagination size="small" v-model:current-page="currentPage" v-model:page-size="pageSize"
                :page-sizes="[1, 2, 3, 5, 10, 20, 30]" :pager-count="3" background @size-change="handleSizeChange"
                @current-change="handleCurrentChange" layout="total, sizes,prev, pager, next" :total="total" />

参考:可选值必须要大于等于 5 且小于等于 21 的奇数

解决:将分页中:pager-count=“3”,改为最小可选值:pager-count="5"即可
