vxe-table 如何自定义校验逻辑，比如第一行和第二行的字段进行关联判断，支持同步/异步自定义方法校验，自定义校验比较灵活，适合用于多字段组合校验。如果是异步时，并发校验的先后顺序是不确定的。

通过 validator 该方法来实现自定义逻辑，方法接收 { row, column, cellValue } 等信息，如果需要和其他行进行判断，可以通过 getTableData 方法获取当前表格数据然后进行多行判断

<template>
  <div>
    <div>
      <vxe-button @click="validEvent">校验变动数据</vxe-button>
      <vxe-button @click="fullValidEvent">校验全量数据</vxe-button>
    </div>
    <vxe-grid ref="gridRef" v-bind="gridOptions"></vxe-grid>
  </div>
</template>
