vxe-table 虚拟树、树形表格的使用

vxe-table 虚拟树、树形表格的使用

如果开启虚拟树，只需要设置 y-scroll.gt（纵向虚拟滚动，默认100）或 x-scroll.gt （横向虚拟是滚动）

transform 自动将列表转换为树结构
rowField 行的主键(模式id)
parentField 行的父级主键(模式parentId)

<vxe-table
   :tree-config="{transform:true}"
   :data="tableData">
   <vxe-column field="name" title="Name" tree-node>vxe-column>
   <vxe-column field="size" title="Size">vxe-column>
   <vxe-column field="type" title="Type">vxe-column>
   <vxe-column field="date" title="Date">vxe-column>
 vxe-table>
