/give @a[score_craftedTable_min=1] minecraft:crafting_table 1 1 {CanPlaceOn:["minecraft:stone"]}

Put a chain command block after it:

/scoreboard players remove @a[score_craftedTable_min=1] craftedTable 1

Then another one with this command (to remove the old crafting tables):

/clear @a minecraft:crafting_table 0
