Nested value does not work properly

[trungkien210493]

Describe the bug
Based on the behavior of grafana, the datasource seems to use the first row to define the table structure (if the first row is not null, it can display properly). Then, when the first row with the nested value is null, the table will display only the name of nested value, not flatten this value.

Expected behavior
The datasource should able to find the table structure from from the query or the all elements of result.

Thanks for reporting this issue. It's definitely a bit tricky, and for sure the "right" thing to do is use the query/schema to determine the data frame structure (see also #13).

@retzkek Thank you for your response. In my opinion, it is easier if you use a loop in the result from query to find the table structure because the result is in "json" format, there are a lot of library to parse it. The query parser is not easy to code and generate the table structure from the parser (I'm a Python Developer and I also tried to parse the Graphql query with the "graphql" Python library and it is very hard )
