Table built question

tmas

First, I built my table 5 years ago. It is time to sand it and restain and I might add a drawer and few other accessories. 

Question: how do I make the table top (4 inch wood planks) to be seamless so water, etc does not run do the the next level?

thanks.

You can probably use a chalk but it won't look good.place sheet of plywood over the planks or have a sheet of ss steal cut and place it on the top.Use your imagination, you can figure out.
good luck
