Its a very pretty table. Yes I would cut your losses and sand the table top again to remove everything, so you can start again with a clean slate.Its hard to judge by a picture, but It looks as the original surface of the table may have had cracks in the surface/finish? In cases like this you need to either sand the surface to remove the old finish or apply several (4) coats of chalk paint to fill any of the holes and cover up the cracks, leave to dry and then you can apply several poly coats.Take your time and ensure you read and follow the instructions on the paint tin.Keep having fun! -

You should have used polycrylic paint instead -

Sounds like there was a chemical reaction between the chalk paint and sealer. I would resand and repaint and use a sealer that is compatible with chalk paint. I would also try procedure on a scrap piece of wood before applying to table top just to make sure it is what you want. Like a sample piece.
