SQL cell's result doesn't export

Hello,

Today I've installed jupyter and beakerx (using pip, following the documentation).
Following that I've been able to connect to a database of mine and to show the result of a very simple query. The notebook just behave as I expect it to : I type my SQL command, evaluate the cell and a nice table with the result appears below the cell.

Now, I try to "print preview" and "file -> download as -> html". Both show me the SQL code I've typed in cells but not the result of the SQL evaluation (i.e. the result table). Is that normal ?

Best regards,

Stefan
