I found the seating on stage for the Nobels ceremony:

For the banquets in the recent past, the SRF did sit close and across from spouses. This year it's married ins on one side and blood royals on the other with the king and queen in the middle.
This year the king, Daniel, Carl Philip, Chris and princess Christina sit on the other side of the table. The queen, Victoria, Madeleine and Sofia on the other side. At the banquets the king and queen sit always in the middle, across each other. The queen has the Chairman of the Board of the Nobel Foundation on her other side, and the king has the wife of the Chairman of the Board of the Nobel Foundation on his other side. There isn't any rule that for instance Victoria and Daniel should every year sit across the table opposite to each other.
The seating plan is a little different every year. The main rule is that two men or two women don't sit beside each other, it is always a man, a woman, a man, a woman.
They try to place the Laureates beside a royal every year, but there are other things to be considered, for instance the languages people speak.
