🐛 Bugfix

• Solve the issue and closes 🐛使用 asyncGetAllPlainData 导出的数据与表格渲染结果不一致 #2808,🤔 rowCell和colCell中对数据String()处理后导致拿不到原始值 #2766,🐛数据为 null, ‘null’和‘’ 的呈现不一致 #2833

📝 Description

  {
    "number": 7789,
    "province": null,
    "city": null,
    "type": null,
    "sub_type": null
  }

维值为空时, null 会转换成 字符串的 "null", 转换前增加标识, 避免原始值丢失, 解决两个问题

{
-  id: 'root[&]null',
-  value: 'null'

+  id: 'root[&]$$null$$',
+  value: null
}

1. 行列头 展示/导出 placehoder 不生效的问题
2. 单元格文本展示成 null 的问题
