Getting rid of the Sheet scroller when a sheet is embedded in a Squarespace

I have embedded a sheet cell into a website, but am struggling to remove some of the uglier aspects of the embed. I dont know much at all about coding, just trying to get the grey bar at the bottom with the two arrows in the corner to go away. Getting rid of the sheets title would be nice (white box with two colons), hoping it would get removed w/ the scroll bar. also if there was any way to remove the weird grey and white boarder i would appreciate that 

Also here's the code for the embed 

<iframe src="https://docs.google.com/spreadsheets...

&amp;single=true&amp;widget=true&amp;headers=false"
scrolling="no"
  width="100%" 
     height="90px"
  overflow=-30
  ></iframe>
