Lots of blank space on card with table

Using the Timeline template, I am creating a table within the day cards to delineate the hours of the day. When doing so, the final rendering of the card appears to have a large amount of space (about as big as the table) between the card heading and the table beginning.

Included are two images: the left is the rendered view and the right is the editing view. Any suggestions to shrink the empty space?
