Javascript 引导Vue更改b表中每个单元格的背景

我正在使用引导vue b-table显示我的项目：

<b-table striped bordered :tbody-tr-class="row_class" :fields="fields" :items="items" head-variant="light" class="o-list"
    thead-class="o-gradient-header"
    @row-selected="onRowSelected" selectable
    no-local-sorting @sort-changed="change_sort" :sort-by="list_options.sort"
    :sort-desc="list_options.order==='desc'">

...

</b-table>

但这会改变整行的样式。我不想那样。我只想改变牢房的样式？有什么方法可以更改每个单元格的背景颜色吗？

您可以使用

tbody tr class

prop设置每一行的样式

<b-table striped hover caption-top
          :items="items"
          :fields="fields"
          :tbody-tr-class="rowClass"
    >
    </b-table>

    },
    methods: {
      rowClass(item, type) {
        if (!item || type !== 'row') return
        if (item.age > 30) return 'table-success'
      }
    }
  });
