一、样式效果 

二、代码

1、wxml

<view class="line flex flex-center">
  <view class="none" wx:if="{{info.length == 0}}">暂无料号</view>
  <view wx:else class="table-container">
    <!-- 动态生成表头 -->
    <view class="table-header-wrapper">
      <view class="table-header flex">
        <view wx:for="{{tableColumns}}" wx:key="key" class="th" style="flex: 0 0 {{item.width}}; min-width: {{item.width}};">
          {{item.title}}
        </view>
      </view>
    </view>
    <!-- 表格数据行 -->
    <view class="table-body-wrapper">
      <view class="table-body">
        <view class="table-row flex {{rowData.checked ? 'row-selected' : ''}}" wx:for="{{info}}" wx:key="index" wx:for-item="rowData" data-id="{{rowData.id}}">
          <view wx:for="{{tableColumns}}" wx:key="key" wx:for-item="colConfig" class="td" style="flex: 0 0 {{colConfig.width}}; min-width: {{colConfig.width}};">
            <block wx:if="{{colConfig.key === 'checked'}}">
              <checkbox value="{{rowData.id}}" checked="{{rowData.checked}}" bindtap="handleSelectItem" data-id="{{rowData.id}}" />
            </block>
            <block wx:elif="{{colConfig.editable}}">
              <!-- 新增判断条件 -->
              <input type="number" value="{{rowData[colConfig.key]}}" placeholder="请输入" bindinput="handleInputChange" data-id="{{rowData.id}}" data-index="{{index}}" data-key="{{colConfig.key}}" />
            </block>
            <block wx:else>
              {{rowData[colConfig.key] || '--'}}
            </block>
          </view>
        </view>
      </view>
    </view>
  </view>
</view>
<view class="btn" bindtap="submitCheckedItems">
  提交
</view>
