vue.js - 为什么我在表中的标题不粘，我正在使用 bootstrap-vue

问题描述

为什么我在表格中的标题不粘，我使用的是 bootstrap-vue。我已经放了一个粘性标题，当我删除粘性标题中的 320px 时，它会在卡上过期。

<div class="card">
  <div class="card-body">
    <h2 class="card-title text-center">PRODUCTS</h2>
    <div class="row">
      <div class="col-12" style="height: 350px;">
        <b-table
          sticky-header="320px"
          :items="products"
          :fields="table.fields"
          :per-page="table.perPage"
          :current-page="table.currentPage"
          :busy="table.isBusy"
          head-variant="light"
          responsive
        >
          <template #cell(actions)="row">
            <b-button
              size="sm"
              @click="addToOrder(row.item, row.index, $event.target)"
              class="mr-1"
            >
              Add
            </b-button>
          </template>
        </b-table>
      </div>
    </div>
  </div>
</div>

解决方案

我认为您的版本bootstrap是问题所在。我为您的问题准备了一个代码片段，您可以看到一切正常。请检查我与您一起导入的版本。

new Vue({
  el: "#app",
  data() {
    return {
      table: {
        fields: ['heading1', 'heading2', 'heading3'],
        perPage: 30,
        currentPage: 1,
        isBusy: false
      },
      products: [{
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        },
        {
          heading1: 'table cell',
          heading2: 'table cell',
          heading3: 'table cell'
        }
      ]
    }
