bootstrap-vue使用colgroup将列与列标题分组

我必须使用Bootstrap Vue来创建表，如图所示，其设计如图所示。

在此按男性和女性按各自的部分分组，可以使用简单的<td>和<col-group>来完成，

bootstrap-vue文档中有插槽table-colgroup，但是在这种情况下我找不到使用的方法。

我已经在下面的代码段中实现了该表：

Vue.config.productionTip = false
Vue.component('icons', {
  template: '<a><slot></slot></a>'
})
new Vue({
  el: '#app',
  methods: {
    addService() {
      this.model.services.push({});
    }
  },
  computed: {
    sec_a_male: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_a_male) || 0)
      }, 0)
    },
    sec_a_female: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_a_female) || 0)
      }, 0)
    },
    sec_b_male: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_b_male) || 0)
      }, 0)
    },
    sec_b_female: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_b_female) || 0)
      }, 0)
    }
  },
  data: {
    model: {
      services: []
    },
    fields: [{
        key: "class",
        label: "Class"
      },
      {
        key: "section_a_male",
        label: "Male"
      },
      {
        key: "section_a_female",
        label: "Female"
      },
      {
        key: "section_b_male",
        label: "Male"
      },
      {
        key: "section_b_female",
        label: "Male"
      }
    ]
  }
})

这可能会让您入门。您可以将bg-danger类添加到td元素中，也可以将变量/类添加到您的fields数组中。

Vue.config.productionTip = false
Vue.component('icons', {
  template: '<a><slot></slot></a>'
})
new Vue({
  el: '#app',
  methods: {
    addService() {
      this.model.services.push({});
    }
  },
  computed: {
    sec_a_male: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_a_male) || 0)
      }, 0)
    },
    sec_a_female: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_a_female) || 0)
      }, 0)
    },
    sec_b_male: function() {
      return this.model.services.reduce(function(a, c) {
        return a + Number((c.section_b_male) || 0)
      }, 0)
    },
    sec_b_female: function() {

        return a + Number((c.section_b_female) || 0)
      }, 0)
    }

以前boostrap-vue上还没有此功能，新的更改刚刚在当前版本的boostrap-vue v2.0.0-rc.14上发布，该版本支持标题行。

  <b-table responsive bordered striped hover caption-top :fields="fields" :items="model.services" caption-top>
    <template slot="thead-top" slot-scope="{}">
            <tr>
              <th></th>
              <th class="text-center" colspan="2">Section A</th>
              <th class="text-center" colspan="2">Section B</th>
            </tr>
         </template>
  </b-table>

这可以通过使用thead-top插槽来完成，在此进一步解释
