Window with Expanding/Collapsing Table

Good Day Everyone,

I'm probably going to get the terminology wrong, but hopefully my explanation will make sense.

I currently have a window that has a set of buttons on the left side and a table on the right side. Crrently I need to find a way to hide the table when the user does not need/want it. My first thought was to create a seperate window to display the table in, but it was requested to not have it display as a second window. Is there a way to do an expanding/collapsing window within a window? That way if I click on a button on the left to display the table it seems to fold out to display the data, and then have a button to fold it back up when not in use?

Hopefully that makes sense.

I appreciate any advance that can be given.
