请教JS如何改变表格的字体颜色？

[weixin_41101062]

做一个微信小程序，在.wxml中建了一个表格：
<view class="table">
<view class="tr bg-w">
<view class="th">参数</view>
<view class="th">结果</view>
<view class="th">参数</view>
<view class="th">结果</view>
</view>
<block wx:for="{{listData}}"wx:key="{{param1}}">
<view class="tr bg-g" wx:if="{{index %2 ==0}}">
<view class="td" selectable="true">{{item.param1}}</view>
<view class="td" selectable="true">{{item.result1}}</view>
<view class="td" selectable="true">{{item.param2}}</view>
<view class="td" selectable="true">{{item.result2}}</view>
</view>
<view class="tr bg-g2" wx:else>
<view class="td" selectable="true">{{item.param1}}</view>
<view class="td" selectable="true">{{item.result1}}</view>
<view class="td" selectable="true">{{item.param2}}</view>
<view class="td" selectable="true">{{item.result2}}</view>
</view>
</block>
</view>
在计算完结果后，我想根据情况改变部分表格中的字体和颜色，怎么做？比如我只想改变Tt0的颜色，谢谢！
js输出代码：
listData: [
{ "param1": "Pt0", "result1": "度", "param2": "Tt0", "result2": "度" },
{ "param1": "Pt1", "result1": "kPa", "param2": "Wa", "result2": "kg/s" },]
