Presumably you meant "can't"? Two ways: "Favorite" or Clone (not sure which) the symbols and footprints to add them to your personal library; Migrate Std to Pro:  Place the symbol and the footprint into a simple schematic and PCB project then import that from Std into Pro and extract the libraries: 

If by tube "data" you mean spice models then you can't do simulation in Pro anyway. You can simulate in LTspice and then import the .asc file into Pro. The EasyEDA spice models all run in LTspice. Contact me at my username at easyeda.com for more info.
