spacing top & bottom

I’m using the overview widget on my homepage, and for some reason, it leaves some spacing above and below. So far I haven’t found where to adjust it yet…

You can see what I mean here: https://test.gaverzicht.be.

I’d also like to know where I can change the general styling of the table.

thanks!
