This.  Some waterproofing treatments are thin as water and need to soak into the wood grain.  Some are like oil.  Others are like polyurethane or varnish.

Water based polyurethane and shellac are not recommended for table tops because they are sensitive to heat.  You can't sit anything hot on them.

So I recommend a varnish or oil based polyurethane.
