printing a table

Hi! Lovely and minimal plugin, thanks!
I just want to print a table form a gravity forms directory plugin.
I can show the icon and just print the table, but i can’ t show it properly.
Can I add some css? I just need to define the border size, text- align and th height, is it possible?
Thanks in advance!
Congratulations for the plugin.
