Datagrid does not show up when nested to tab component

Hi,

I have a datagrid that I need to display into a tab but nothing is shown even datagrid headers. I have no error in logs.

Can anybody help?
I joined my code and a screen capture of my problem.

Hi.
Could you please provide more information about your problem? Which version of the platform do you use?
Maybe you may see some problems in the browser developer console?

Regards,
Natalia
