the side of the table that causes it to break when a block is placed on top of section 0
you can also place the block first then place the table to do this but
breaking the block when you managed to do this will also cause the table to break

here what i have done is break section 1 of the table however the other side is still there it can still be stood on however you cant break the table properly from that end anymore
and as you can also see here is that i am manageing to break stuff through the tables broken section 1 aswell

this also lets you place blocks inside the broken section 1
