I'm trying to make a sort of table, but instead of all the columns ending in the same row, the border should be just underneath the last item in the table.

An example would be:

At the moment, I'm doing this manually by drawing borders around each of the columns, but this doesn't seem to be the most efficient way of doing this. Is there was a way to make it so that the borders surround the outside of the block of cells, perhaps using conditional formatting?

Ideally, this would allow me to add another element to one of the columns and the border would automatically accommodate for this.
