uniapp 写微信小程序 使用uni-table 如何固定列？

Question

我使用uniapp写的小程序，使用到了uni-table这个组件

我希望最后一列，更多操作这列可以固定列，该如何写呢？ 求大佬

uni-table的源码

<view class="uni-table" :style="{ 'min-width': minWidth + 'px' }" :class="{ 'table--stripe': stripe }">
            <slot></slot>
            <view v-if="noData" class="uni-table-loading">
                <view class="uni-table-text" :class="{ 'empty-border': border }">{{ emptyText }}</view>
            </view>
            <view v-if="loading" class="uni-table-mask" :class="{ 'empty-border': border }"><div class="uni-table--loader"></div></view>
        </view>

uni-tr 的源码

<view class="uni-table-tr">
        <view v-if="selection === 'selection' " class="checkbox" :class="{ 'tr-table--border': border }">
            <table-checkbox :checked="checked" :indeterminate="indeterminate" :disabled="disabled" @checkboxSelected="checkboxSelected"></table-checkbox>
        </view>
        <slot></slot>
    </view>

uni-td的源码

<view class="uni-table-td" :class="{'table--border':border}" :style="{width:width + 'px','text-align':align}">
        <slot></slot>
    </view>

这是我调用的代码

<uni-table ref="table" :loading="loading" border stripe emptyText="暂无更多数据">
                <uni-tr class="sticky">
                    <uni-th width="150" align="center">下单时间</uni-th>
                    <uni-th width="150" align="center">下单编号</uni-th>
                    <uni-th align="center">子单编号</uni-th>
                    <uni-th width="100" align="center">操作</uni-th>
                </uni-tr>
                <uni-tr v-for="(item, index) in tableData" :key="index">
                    <uni-td>{{ item.date }}</uni-td>
                    <uni-td>
                        <view class="name">{{ item.name }}</view>
                    </uni-td>
                    <uni-td align="center">{{ item.address }}</uni-td>
                    <uni-td align="center">
                        <view class="uni-group">
                            <p>更多操作</p>
                            <!-- <view class="actions">
                                <p>签署/下载函件</p>
                                <p>上传图片</p>
                                <p>上传PDF</p>
                            </view> -->
                        </view>
                    </uni-td>
                </uni-tr>
            </uni-table>
