CSS类没有得到应用到表行

Question

下面是中使用的CSS类：

.table-striped>tbody>tr:last-child>td, 
.table-striped>tbody>tr:last-child>th>.total_row_dark { 
    background-color: #76767b !important; 
    color: #fff; 
    font-weight: 700; 
} 

tr.campare_row span { 
    background-color: #76767b; 
    border-radius: 5px; 
    color: #ffffff !important; 
    display: inline-block; 
    font-weight: bold; 
    margin: 3px; 
    padding: 6px 18px; 
    font-size: 16px; 
    border: 1px solid #ffffff; 
} 

.campare_row>td { 
    vertical-align: middle!important; 
} 

这些类都应该在这里被用于以下表行：

<tr class="campare_row total_row_dark" ng-repeat="location in vm.rwsTableData | filter : 'Summary'" ts-repeat> 
    <td> </td> 
    <td class="text-left">{{location.locationName}}</td> 
    <td class="text-right light-blue">{{(location.waterDemand == vm.constant.NO_WATER_SUPPLY)?'-':location.waterDemand | number:2}}</td> 
    <td class="text-right light-blue">{{(location.waterSupply == vm.constant.NO_WATER_SUPPLY)?'-':location.waterSupply | number:2}}</td> 
    <td class="text-right light-blue" ng-if="location.waterDemand != vm.constant.NO_WATER_SUPPLY && location.waterDeficit != vm.constant.NO_WATER_SUPPLY">{{(location.waterDeficit == vm.constant.NO_WATER_SUPPLY)?'-':location.waterDeficit | number:2}} ({{(location.waterDemand != 0)?((location.waterDeficit*100)/location.waterDemand):0 | number:2}}%)</td> 
    <td class="text-right light-blue" ng-if="location.waterDemand == vm.constant.NO_WATER_SUPPLY || location.waterDeficit == vm.constant.NO_WATER_SUPPLY">{{(location.waterDeficit == vm.constant.NO_WATER_SUPPLY)?'-':(location.waterDeficit | number:2)}}</td> 
    <td class="text-right light-orange">{{vm.getStressValue(location.locationStressIndicator)}}</td> 
    <td class="text-right light-orange">{{location.impactedPopulation | number}}</td> 
    <td class="text-right light-blue">{{location.numOfTankersAsOfToday | number}}</td> 
    <td class="text-right light-blue">{{location.numOfTankersForToday | number}}</td> 
    <td></td> 
</tr> 

根据类的描述，表中的最后一行应分别改为所提到的背景颜色，文本颜色和字体权重。但它并没有改变，最后一行是整个桌子的颜色。如何解决这个问题？
