数据在表格中。有时您会看到以下消息：

此表的流缓冲区中的记录可能无法在预览中看到。

Web UI是显示流式或更新表格细节的小错误。如果您运行查询，您将看到您期望的数据。

After streaming data in BigQuery, new data is available only for few moments in the table as I refresh the page data is gone but I can still query.The main problem is every time I am closing the tab and again access it from the storage I can see the data in table but again it goes when I refresh the page.

The data is in the table. Sometimes you will see the message:

This table has records in the streaming buffer that may not be visible in the preview.

The web UI is little buggy with displaying streamed or updated table details. If you run your query you will see the data you expect.
