<template>
  <div>
    <p>海量数据</p>
    <p>大数据不建议使用双向绑定的 data 属性（vue 监听会大数据会短暂的卡顿），建议使用 load 函数</p>
    <p>实际渲染速度受以下影响：多选(超严重)、固定列(严重)、底部合计(中度)、数据运算量(轻度)、任何双向的数据或函数都会影响加载速度</p>

    <vxe-table
      border
      highlight-hover-row
      height="300"
      :data.sync="tableData">
      <vxe-table-column type="index" width="100"></vxe-table-column>
      <vxe-table-column prop="name" label="Name" sortable></vxe-table-column>
      <vxe-table-column prop="sex" label="Sex"></vxe-table-column>
      <vxe-table-column prop="age" label="Age"></vxe-table-column>
      <vxe-table-column prop="address" label="Address" show-overflow></vxe-table-column>
    </vxe-table>

    <p class="demo-code">显示代码</p>

    <pre>
      <code class="xml">{{ demoCodes[0] }}</code>
      <code class="javascript">{{ demoCodes[1] }}</code>
    </pre>

    <p>高级配置项</p>
    <p>参数 scrollX: {gt: 16, oSize: 4, rSize: 10},scrollY: {gt: 500, oSize: 30, rSize: 80}，当数据量过大时请调整到适合的参数可以使渲染更快</p>
    <p>数据超大情况下必须使用：show-all-overflow,show-header-all-overflow 参数以及调整好 optimized：{scrollX,scrollY} 适合的参数可以更加流畅</p>
