How to fix the gaps in this wood panel?

[Jen_Andrew]

A friend gave me a wood panel (length 1120mm, width 605mm, thickness 26mm) that I was thinking of making into an outdoor table by adding premade steel furniture legs and finishing in an outdoor oil coating. I left the wood under my awning and when it rained, it still got very wet. I took it inside but since then, I noticed at about 3 or 4 spots there are very thin gaps  in the panel where the individual wood "slats"have been glued together (see photos). These gaps are full thickness, with the longest one being about 6-7cm. Do I need to fix/fill in these gaps? If so, how?

Hi @Jen_Andrew,

Nice work!

Your table looks fantastic, and you should be very proud of the results.

Thanks for sharing your photos.
