<template>
  <div>
    <p>树表格，通过配置 <table-api-link prop="tree-config"/> 和指定列 <table-column-api-link prop="tree-node"/> 属性来开启树表格</p>
    <p>还可以通过 <table-api-link prop="trigger"/> 指定触发方式</p>

    <vxe-table
      border
      resizable
      :tree-config="{children: 'children'}"
      :data.sync="tableData">
      <vxe-table-column field="name" title="app.body.label.name"></vxe-table-column>
      <vxe-table-column field="size" title="Size"></vxe-table-column>
      <vxe-table-column field="type" title="Type"></vxe-table-column>
      <vxe-table-column field="date" title="Date" tree-node></vxe-table-column>

    <p class="demo-code">{{ $t('app.body.button.showCode') }}</p>

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

    <p>默认展开所有树节点，通过 <table-api-link prop="expand-config"/> 参数设置默认展开树节点</p>
