Power BI features - visual help

Hi everyone! I was asked to include two changes in my Power BI dashboard but I am not sure if this is possible (I couldn´t find both features in power bi):

1) Is it possible to leave the first column of a table/matrix freezed? Like in an Excel table when you freeze a column, and when you move throw other columns you keep the first one visible.

2) Is it possible to add in a table/matrix a + to see more data if you want to? for example:

+ Food

and if you click the +:

+ Food

   Vegetables

   Fruits

Thanks!!!
